Let's divide 854972 by 87
The aim is to understand the frequency of 87 in 854972.

Advancing to step 1:
The number 87 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 87

Going ahead to step 2:
If we divide 85 by 87, we get 0 and a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Append the next digit (4) from the dividend to 85 and continue with: 854 / 87

Step 3:
If we divide 854 by 87, we get 9 and a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 783 from 854, we get 71.
Fetch the next digit (9) from the dividend, attach it to 71 and continue: 719 / 87

Advancing to step 4:
87 goes into 719 8 times with a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
The remainder is 23 after subtracting 696 from 719.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 87

Moving on to step 5:
When dividing 237 by 87, we get 2 with a remainder of 63.
Use 2 as the next digit of our solution. 
Result so far: 982.0
Subtracting 174 from 237 leaves us with 63.
Grab the next digit (2) from the dividend, add it to 63, then carry on: 632 / 87

Moving on to step 6:
87 goes into 632 7 times with a remainder of 23.
The next digit of our result is 7. 
Result so far: 9827.0
The remainder is 23 after subtracting 609 from 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
87 can be fit into 230 2 times, resulting in a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 9827.2
Subtracting 174 from 230 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 8:
When dividing 560 by 87, we get 6 with a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 9827.26
The remainder is 38 after subtracting 522 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 9:
87 goes into 380 4 times with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 9827.264
Subtracting 348 from 380 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
320 divided by 87 is 3 with a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 9827.2643
If we take 261 away from 320, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 11:
87 can be fit into 590 6 times, resulting in a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 9827.26436
Deduct 522 from 590 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 12:
87 can be fit into 680 7 times, resulting in a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 9827.264367
Subtract 609 from 680 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 13:
When dividing 710 by 87, we get 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 9827.2643678
If we take 696 away from 710, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 14:
The number 87 fits into 140 1 times, leaving a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 9827.26436781
Subtracting 87 from 140 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Our division results in 9827.26436781 with a remaining 5.3e-08.
