We're dividing 61590057 by 881 
The aim is to understand the frequency of 881 in 61590057.

Going ahead to step 1:
If we divide 6 by 881, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 881

Let's proceed to step 2:
The number 881 fits into 61 0 times, leaving a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Take the next digit (5) from the dividend and append it to 61, then repeat: 615 / 881

Going ahead to step 3:
If we divide 615 by 881, we get 0 and a remainder of 615.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 615 and we're left with 615.
Append the next digit (9) from the dividend to 615 and continue with: 6159 / 881

Advancing to step 4:
881 can be fit into 6159 6 times, resulting in a remainder of 873.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 5286 away from 6159, we end up with 873.
Take the next digit (0) from the dividend and append it to 873, then repeat: 8730 / 881

Let's proceed to step 5:
The number 881 fits into 8730 9 times, leaving a remainder of 801.
The next digit of our result is 9. 
Result so far: 69.0
If we take 7929 away from 8730, we end up with 801.
Append the next digit (0) from the dividend to 801 and continue with: 8010 / 881

Advancing to step 6:
If we divide 8010 by 881, we get 9 and a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 699.0
The remainder is 81 after subtracting 7929 from 8010.
Fetch the next digit (5) from the dividend, attach it to 81 and continue: 815 / 881

Going ahead to step 7:
881 goes into 815 0 times with a remainder of 815.
The number 0 becomes the next digit in our result. 
Result so far: 6990.0
Deduct 0 from 815 and we're left with 815.
Grab the next digit (7) from the dividend, add it to 815, then carry on: 8157 / 881

On to step 8:
If we divide 8157 by 881, we get 9 and a remainder of 228.
Write down 9 as next digit of the result. 
Result so far: 69909.0
The remainder is 228 after subtracting 7929 from 8157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 9:
881 can be fit into 2280 2 times, resulting in a remainder of 518.
Record the quotient 2 as the next digit in the result. 
Result so far: 69909.2
Subtract 1762 from 2280 to get 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Let's proceed to step 10:
881 can be fit into 5180 5 times, resulting in a remainder of 775.
The number 5 becomes the next digit in our result. 
Result so far: 69909.25
If we take 4405 away from 5180, we end up with 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

On to step 11:
If we divide 7750 by 881, we get 8 and a remainder of 702.
Write down 8 as next digit of the result. 
Result so far: 69909.258
If we take 7048 away from 7750, we end up with 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Step 12:
When dividing 7020 by 881, we get 7 with a remainder of 853.
Write down 7 as next digit of the result. 
Result so far: 69909.2587
Subtract 6167 from 7020 to get 853.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8530, and continue the process.

Step 13:
When dividing 8530 by 881, we get 9 with a remainder of 601.
Use 9 as the next digit of our solution. 
Result so far: 69909.25879
Deduct 7929 from 8530 and we're left with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

On to step 14:
The number 881 fits into 6010 6 times, leaving a remainder of 724.
Record the quotient 6 as the next digit in the result. 
Result so far: 69909.258796
If we take 5286 away from 6010, we end up with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

On to step 15:
881 can be fit into 7240 8 times, resulting in a remainder of 192.
Put 8 as the next digit of the answer. 
Result so far: 69909.2587968
Deduct 7048 from 7240 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 16:
The number 881 fits into 1920 2 times, leaving a remainder of 158.
Write down 2 as next digit of the result. 
Result so far: 69909.25879682
The remainder is 158 after subtracting 1762 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

After the division, we end up with 69909.25879682 and a remainder of 1.58e-07.
