We're dividing 53684751 by 863 
The aim is to understand the frequency of 863 in 53684751.

Let's proceed to step 1:
When dividing 5 by 863, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 863

Let's proceed to step 2:
863 goes into 53 0 times with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Take the next digit (6) from the dividend and append it to 53, then repeat: 536 / 863

On to step 3:
536 divided by 863 is 0 with a remainder of 536.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 536 leaves us with 536.
Grab the next digit (8) from the dividend, add it to 536, then carry on: 5368 / 863

Advancing to step 4:
863 goes into 5368 6 times with a remainder of 190.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 5178 from 5368 leaves us with 190.
Bring next digit (4) of the dividend behind the 190 and repeat the process: 1904 / 863

Let's proceed to step 5:
When dividing 1904 by 863, we get 2 with a remainder of 178.
Write down 2 as next digit of the result. 
Result so far: 62.0
Deduct 1726 from 1904 and we're left with 178.
Fetch the next digit (7) from the dividend, attach it to 178 and continue: 1787 / 863

Moving on to step 6:
863 can be fit into 1787 2 times, resulting in a remainder of 61.
Record the quotient 2 as the next digit in the result. 
Result so far: 622.0
Subtracting 1726 from 1787 leaves us with 61.
Append the next digit (5) from the dividend to 61 and continue with: 615 / 863

On to step 7:
863 can be fit into 615 0 times, resulting in a remainder of 615.
The next digit of our result is 0. 
Result so far: 6220.0
If we take 0 away from 615, we end up with 615.
Append the next digit (1) from the dividend to 615 and continue with: 6151 / 863

Let's proceed to step 8:
863 goes into 6151 7 times with a remainder of 110.
Record the quotient 7 as the next digit in the result. 
Result so far: 62207.0
The remainder is 110 after subtracting 6041 from 6151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 9:
863 goes into 1100 1 times with a remainder of 237.
The next digit of our result is 1. 
Result so far: 62207.1
If we take 863 away from 1100, we end up with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Step 10:
2370 divided by 863 is 2 with a remainder of 644.
Use 2 as the next digit of our solution. 
Result so far: 62207.12
Subtract 1726 from 2370 to get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Step 11:
863 goes into 6440 7 times with a remainder of 399.
Record the quotient 7 as the next digit in the result. 
Result so far: 62207.127
The remainder is 399 after subtracting 6041 from 6440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

On to step 12:
When dividing 3990 by 863, we get 4 with a remainder of 538.
The number 4 becomes the next digit in our result. 
Result so far: 62207.1274
If we subtract 3452 from 3990, we get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Moving on to step 13:
If we divide 5380 by 863, we get 6 and a remainder of 202.
The number 6 becomes the next digit in our result. 
Result so far: 62207.12746
Deduct 5178 from 5380 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 14:
863 can be fit into 2020 2 times, resulting in a remainder of 294.
The next digit of our result is 2. 
Result so far: 62207.127462
If we take 1726 away from 2020, we end up with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 15:
863 goes into 2940 3 times with a remainder of 351.
Use 3 as the next digit of our solution. 
Result so far: 62207.1274623
The remainder is 351 after subtracting 2589 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Moving on to step 16:
863 can be fit into 3510 4 times, resulting in a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 62207.12746234
Subtracting 3452 from 3510 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final outcome is 62207.12746234, with a leftover of 5.8e-08.
