We divide 86850491 by 863
The aim is to understand the frequency of 863 in 86850491.

On to step 1:
863 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 863

Moving on to step 2:
If we divide 86 by 863, we get 0 and a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Grab the next digit (8) from the dividend, add it to 86, then carry on: 868 / 863

On to step 3:
When dividing 868 by 863, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 863 from 868 leaves us with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 863

Step 4:
55 divided by 863 is 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 55 leaves us with 55.
Fetch the next digit (0) from the dividend, attach it to 55 and continue: 550 / 863

Step 5:
863 can be fit into 550 0 times, resulting in a remainder of 550.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Deduct 0 from 550 and we're left with 550.
Bring next digit (4) of the dividend behind the 550 and repeat the process: 5504 / 863

Step 6:
863 can be fit into 5504 6 times, resulting in a remainder of 326.
Use 6 as the next digit of our solution. 
Result so far: 1006.0
Subtracting 5178 from 5504 leaves us with 326.
Include the next digit (9) from the dividend after 326, then repeat: 3269 / 863

Step 7:
863 goes into 3269 3 times with a remainder of 680.
The number 3 becomes the next digit in our result. 
Result so far: 10063.0
If we subtract 2589 from 3269, we get 680.
Take the next digit (1) from the dividend and append it to 680, then repeat: 6801 / 863

Advancing to step 8:
863 goes into 6801 7 times with a remainder of 760.
Put 7 as the next digit of the answer. 
Result so far: 100637.0
If we subtract 6041 from 6801, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Going ahead to step 9:
863 goes into 7600 8 times with a remainder of 696.
The next digit of our result is 8. 
Result so far: 100637.8
If we take 6904 away from 7600, we end up with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Advancing to step 10:
When dividing 6960 by 863, we get 8 with a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 100637.88
Subtracting 6904 from 6960 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.

The final result is 100637.88 with a remainder of 0.056.
