Let's divide 53199934 by 861
The aim is to understand the frequency of 861 in 53199934.

On to step 1:
861 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 861

Going ahead to step 2:
The number 861 fits into 53 0 times, leaving a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 861

Going ahead to step 3:
531 divided by 861 is 0 with a remainder of 531.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 531 and we're left with 531.
Append the next digit (9) from the dividend to 531 and continue with: 5319 / 861

Advancing to step 4:
When dividing 5319 by 861, we get 6 with a remainder of 153.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 153 after subtracting 5166 from 5319.
Grab the next digit (9) from the dividend, add it to 153, then carry on: 1539 / 861

Step 5:
861 goes into 1539 1 times with a remainder of 678.
Put 1 as the next digit of the answer. 
Result so far: 61.0
If we take 861 away from 1539, we end up with 678.
Bring next digit (9) of the dividend behind the 678 and repeat the process: 6789 / 861

Going ahead to step 6:
861 goes into 6789 7 times with a remainder of 762.
Use 7 as the next digit of our solution. 
Result so far: 617.0
If we subtract 6027 from 6789, we get 762.
Take the next digit (3) from the dividend and append it to 762, then repeat: 7623 / 861

Step 7:
861 goes into 7623 8 times with a remainder of 735.
Record the quotient 8 as the next digit in the result. 
Result so far: 6178.0
Subtracting 6888 from 7623 leaves us with 735.
Fetch the next digit (4) from the dividend, attach it to 735 and continue: 7354 / 861

Step 8:
7354 divided by 861 is 8 with a remainder of 466.
Use 8 as the next digit of our solution. 
Result so far: 61788.0
Subtracting 6888 from 7354 leaves us with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Advancing to step 9:
4660 divided by 861 is 5 with a remainder of 355.
The number 5 becomes the next digit in our result. 
Result so far: 61788.5
If we subtract 4305 from 4660, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Going ahead to step 10:
861 can be fit into 3550 4 times, resulting in a remainder of 106.
Record the quotient 4 as the next digit in the result. 
Result so far: 61788.54
Deduct 3444 from 3550 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 11:
861 can be fit into 1060 1 times, resulting in a remainder of 199.
Write down 1 as next digit of the result. 
Result so far: 61788.541
Deduct 861 from 1060 and we're left with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Going ahead to step 12:
The number 861 fits into 1990 2 times, leaving a remainder of 268.
Use 2 as the next digit of our solution. 
Result so far: 61788.5412
Subtracting 1722 from 1990 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Step 13:
861 goes into 2680 3 times with a remainder of 97.
Record the quotient 3 as the next digit in the result. 
Result so far: 61788.54123
Subtracting 2583 from 2680 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 14:
970 divided by 861 is 1 with a remainder of 109.
Write down 1 as next digit of the result. 
Result so far: 61788.541231
The remainder is 109 after subtracting 861 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 15:
The number 861 fits into 1090 1 times, leaving a remainder of 229.
The number 1 becomes the next digit in our result. 
Result so far: 61788.5412311
Deduct 861 from 1090 and we're left with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

The final outcome is 61788.5412311, with a leftover of 2.29e-06.
