We're dividing 911617 by 87 
The aim is to understand the frequency of 87 in 911617.

Step 1:
If we divide 9 by 87, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 87

Let's proceed to step 2:
87 can be fit into 91 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 87 away from 91, we end up with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 87

Advancing to step 3:
41 divided by 87 is 0 with a remainder of 41.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 41, we get 41.
Fetch the next digit (6) from the dividend, attach it to 41 and continue: 416 / 87

Step 4:
416 divided by 87 is 4 with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Subtract 348 from 416 to get 68.
Fetch the next digit (1) from the dividend, attach it to 68 and continue: 681 / 87

Going ahead to step 5:
87 can be fit into 681 7 times, resulting in a remainder of 72.
Record the quotient 7 as the next digit in the result. 
Result so far: 1047.0
The remainder is 72 after subtracting 609 from 681.
Take the next digit (7) from the dividend and append it to 72, then repeat: 727 / 87

Advancing to step 6:
The number 87 fits into 727 8 times, leaving a remainder of 31.
Put 8 as the next digit of the answer. 
Result so far: 10478.0
If we subtract 696 from 727, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
310 divided by 87 is 3 with a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 10478.3
If we subtract 261 from 310, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 8:
The number 87 fits into 490 5 times, leaving a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 10478.35
If we subtract 435 from 490, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 9:
87 goes into 550 6 times with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 10478.356
Subtracting 522 from 550 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
When dividing 280 by 87, we get 3 with a remainder of 19.
The next digit of our result is 3. 
Result so far: 10478.3563
Subtract 261 from 280 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 11:
87 can be fit into 190 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 10478.35632
Subtract 174 from 190 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
87 goes into 160 1 times with a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 10478.356321
Subtract 87 from 160 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 13:
The number 87 fits into 730 8 times, leaving a remainder of 34.
The next digit of our result is 8. 
Result so far: 10478.3563218
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.

Advancing to step 14:
When dividing 340 by 87, we get 3 with a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 10478.35632183
Subtract 261 from 340 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

The final outcome is 10478.35632183, with a leftover of 7.9e-08.
