883847 ÷ 87 
The aim is to understand the frequency of 87 in 883847.

On to step 1:
When dividing 8 by 87, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 87

Advancing to step 2:
The number 87 fits into 88 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 87 from 88 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 87

On to step 3:
If we divide 13 by 87, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 87

Advancing to step 4:
138 divided by 87 is 1 with a remainder of 51.
The next digit of our result is 1. 
Result so far: 101.0
Subtract 87 from 138 to get 51.
Fetch the next digit (4) from the dividend, attach it to 51 and continue: 514 / 87

Let's proceed to step 5:
87 goes into 514 5 times with a remainder of 79.
Put 5 as the next digit of the answer. 
Result so far: 1015.0
Subtracting 435 from 514 leaves us with 79.
Grab the next digit (7) from the dividend, add it to 79, then carry on: 797 / 87

Going ahead to step 6:
87 goes into 797 9 times with a remainder of 14.
The next digit of our result is 9. 
Result so far: 10159.0
If we subtract 783 from 797, 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.

Going ahead to step 7:
When dividing 140 by 87, we get 1 with a remainder of 53.
The next digit of our result is 1. 
Result so far: 10159.1
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.

On to step 8:
The number 87 fits into 530 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 10159.16
Subtract 522 from 530 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
The number 87 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 10159.16
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
If we divide 800 by 87, we get 9 and a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 10159.1609
Subtracting 783 from 800 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 11:
If we divide 170 by 87, we get 1 and a remainder of 83.
The number 1 becomes the next digit in our result. 
Result so far: 10159.16091
Deduct 87 from 170 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 12:
87 can be fit into 830 9 times, resulting in a remainder of 47.
The next digit of our result is 9. 
Result so far: 10159.160919
The remainder is 47 after subtracting 783 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 13:
If we divide 470 by 87, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 10159.1609195
The remainder is 35 after subtracting 435 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 14:
87 goes into 350 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 10159.16091954
If we take 348 away from 350, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 10159.16091954 with a remaining 2e-09.
