We divide 617981 by 84
The aim is to understand the frequency of 84 in 617981.

Advancing to step 1:
84 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 84

On to step 2:
84 goes into 61 0 times with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Include the next digit (7) from the dividend after 61, then repeat: 617 / 84

Going ahead to step 3:
When dividing 617 by 84, we get 7 with a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 29 after subtracting 588 from 617.
Fetch the next digit (9) from the dividend, attach it to 29 and continue: 299 / 84

Advancing to step 4:
If we divide 299 by 84, we get 3 and a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Deduct 252 from 299 and we're left with 47.
Grab the next digit (8) from the dividend, add it to 47, then carry on: 478 / 84

On to step 5:
478 divided by 84 is 5 with a remainder of 58.
Put 5 as the next digit of the answer. 
Result so far: 735.0
If we subtract 420 from 478, we get 58.
Bring next digit (1) of the dividend behind the 58 and repeat the process: 581 / 84

Going ahead to step 6:
When dividing 581 by 84, we get 6 with a remainder of 77.
The next digit of our result is 6. 
Result so far: 7356.0
Deduct 504 from 581 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 7:
The number 84 fits into 770 9 times, leaving a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 7356.9
Subtract 756 from 770 to 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.

On to step 8:
The number 84 fits into 140 1 times, leaving a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 7356.91
Subtracting 84 from 140 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.

Going ahead to step 9:
If we divide 560 by 84, we get 6 and a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 7356.916
Deduct 504 from 560 and we're left 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.

Moving on to step 10:
If we divide 560 by 84, we get 6 and a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 7356.9166
If we take 504 away from 560, we end up 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.

After the division, we end up with 7356.9166 and a remainder of 0.00056.
