329480 divided by 87 
The aim is to understand the frequency of 87 in 329480.

On to step 1:
The number 87 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 87

Moving on to step 2:
32 divided by 87 is 0 with a remainder of 32.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 32 and we're left with 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 87

Advancing to step 3:
87 goes into 329 3 times with a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 261 from 329 and we're left with 68.
Include the next digit (4) from the dividend after 68, then repeat: 684 / 87

Advancing to step 4:
When dividing 684 by 87, we get 7 with a remainder of 75.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we take 609 away from 684, we end up with 75.
Take the next digit (8) from the dividend and append it to 75, then repeat: 758 / 87

Step 5:
87 can be fit into 758 8 times, resulting in a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 378.0
Deduct 696 from 758 and we're left with 62.
Include the next digit (0) from the dividend after 62, then repeat: 620 / 87

Moving on to step 6:
87 goes into 620 7 times with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 3787.0
The remainder is 11 after subtracting 609 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
If we divide 110 by 87, we get 1 and a remainder of 23.
The next digit of our result is 1. 
Result so far: 3787.1
If we subtract 87 from 110, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 8:
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: 3787.12
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.

Going ahead to step 9:
If we divide 560 by 87, we get 6 and a remainder of 38.
The next digit of our result is 6. 
Result so far: 3787.126
Deduct 522 from 560 and we're left with 38.
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 10:
If we divide 380 by 87, we get 4 and a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 3787.1264
Subtract 348 from 380 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 11:
320 divided by 87 is 3 with a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 3787.12643
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.

Going ahead to step 12:
When dividing 590 by 87, we get 6 with a remainder of 68.
The next digit of our result is 6. 
Result so far: 3787.126436
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.

Moving on to step 13:
If we divide 680 by 87, we get 7 and a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 3787.1264367
If we take 609 away from 680, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 14:
710 divided by 87 is 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 3787.12643678
If we subtract 696 from 710, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 3787.12643678 with a remaining 1.4e-08.
