Let's divide 857023 by 87
The aim is to understand the frequency of 87 in 857023.

Advancing to step 1:
If we divide 8 by 87, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 87

Let's proceed to step 2:
87 can be fit into 85 0 times, resulting in a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Fetch the next digit (7) from the dividend, attach it to 85 and continue: 857 / 87

Let's proceed to step 3:
87 goes into 857 9 times with a remainder of 74.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 783 from 857 and we're left with 74.
Append the next digit (0) from the dividend to 74 and continue with: 740 / 87

Advancing to step 4:
If we divide 740 by 87, we get 8 and a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 98.0
Subtract 696 from 740 to get 44.
Grab the next digit (2) from the dividend, add it to 44, then carry on: 442 / 87

On to step 5:
If we divide 442 by 87, we get 5 and a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 985.0
Deduct 435 from 442 and we're left with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 87

Moving on to step 6:
87 can be fit into 73 0 times, resulting in a remainder of 73.
The next digit of our result is 0. 
Result so far: 9850.0
If we take 0 away from 73, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 7:
87 goes into 730 8 times with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 9850.8
The remainder is 34 after subtracting 696 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
340 divided by 87 is 3 with a remainder of 79.
The next digit of our result is 3. 
Result so far: 9850.83
Subtracting 261 from 340 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 9:
When dividing 790 by 87, we get 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 9850.839
Subtracting 783 from 790 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
The number 87 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 9850.839
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 11:
87 can be fit into 700 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 9850.83908
Subtracting 696 from 700 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
When dividing 40 by 87, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 9850.83908
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
If we divide 400 by 87, we get 4 and a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 9850.8390804
If we take 348 away from 400, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 14:
520 divided by 87 is 5 with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 9850.83908045
The remainder is 85 after subtracting 435 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Our division results in 9850.83908045 with a remaining 8.5e-08.
