Let's divide 51720939 by 881
The aim is to understand the frequency of 881 in 51720939.

Step 1:
The number 881 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 881

Step 2:
881 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Grab the next digit (7) from the dividend, add it to 51, then carry on: 517 / 881

Let's proceed to step 3:
881 goes into 517 0 times with a remainder of 517.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 517 to get 517.
Include the next digit (2) from the dividend after 517, then repeat: 5172 / 881

Moving on to step 4:
5172 divided by 881 is 5 with a remainder of 767.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 767 after subtracting 4405 from 5172.
Append the next digit (0) from the dividend to 767 and continue with: 7670 / 881

Let's proceed to step 5:
7670 divided by 881 is 8 with a remainder of 622.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
Subtracting 7048 from 7670 leaves us with 622.
Include the next digit (9) from the dividend after 622, then repeat: 6229 / 881

Step 6:
The number 881 fits into 6229 7 times, leaving a remainder of 62.
Put 7 as the next digit of the answer. 
Result so far: 587.0
If we take 6167 away from 6229, we end up with 62.
Fetch the next digit (3) from the dividend, attach it to 62 and continue: 623 / 881

Advancing to step 7:
623 divided by 881 is 0 with a remainder of 623.
Use 0 as the next digit of our solution. 
Result so far: 5870.0
If we take 0 away from 623, we end up with 623.
Grab the next digit (9) from the dividend, add it to 623, then carry on: 6239 / 881

Advancing to step 8:
881 can be fit into 6239 7 times, resulting in a remainder of 72.
Write down 7 as next digit of the result. 
Result so far: 58707.0
If we take 6167 away from 6239, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
881 goes into 720 0 times with a remainder of 720.
Put 0 as the next digit of the answer. 
Result so far: 58707.0
The remainder is 720 after subtracting 0 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 10:
When dividing 7200 by 881, we get 8 with a remainder of 152.
Record the quotient 8 as the next digit in the result. 
Result so far: 58707.08
Subtracting 7048 from 7200 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 11:
881 goes into 1520 1 times with a remainder of 639.
Use 1 as the next digit of our solution. 
Result so far: 58707.081
Subtracting 881 from 1520 leaves us with 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Step 12:
881 can be fit into 6390 7 times, resulting in a remainder of 223.
Use 7 as the next digit of our solution. 
Result so far: 58707.0817
If we take 6167 away from 6390, we end up with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Advancing to step 13:
The number 881 fits into 2230 2 times, leaving a remainder of 468.
The next digit of our result is 2. 
Result so far: 58707.08172
Deduct 1762 from 2230 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

On to step 14:
The number 881 fits into 4680 5 times, leaving a remainder of 275.
Use 5 as the next digit of our solution. 
Result so far: 58707.081725
The remainder is 275 after subtracting 4405 from 4680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 15:
When dividing 2750 by 881, we get 3 with a remainder of 107.
The next digit of our result is 3. 
Result so far: 58707.0817253
If we subtract 2643 from 2750, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Step 16:
When dividing 1070 by 881, we get 1 with a remainder of 189.
Record the quotient 1 as the next digit in the result. 
Result so far: 58707.08172531
The remainder is 189 after subtracting 881 from 1070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

After the division, we end up with 58707.08172531 and a remainder of 1.89e-07.
