Let's divide 551685 by 83
The aim is to understand the frequency of 83 in 551685.

On to step 1:
5 divided by 83 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 83

Going ahead to step 2:
55 divided by 83 is 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Include the next digit (1) from the dividend after 55, then repeat: 551 / 83

Going ahead to step 3:
If we divide 551 by 83, we get 6 and a remainder of 53.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 498 from 551 leaves us with 53.
Grab the next digit (6) from the dividend, add it to 53, then carry on: 536 / 83

Moving on to step 4:
The number 83 fits into 536 6 times, leaving a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
Subtract 498 from 536 to get 38.
Fetch the next digit (8) from the dividend, attach it to 38 and continue: 388 / 83

Advancing to step 5:
83 goes into 388 4 times with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 664.0
Deduct 332 from 388 and we're left with 56.
Take the next digit (5) from the dividend and append it to 56, then repeat: 565 / 83

Advancing to step 6:
83 can be fit into 565 6 times, resulting in a remainder of 67.
The number 6 becomes the next digit in our result. 
Result so far: 6646.0
The remainder is 67 after subtracting 498 from 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 7:
83 can be fit into 670 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 6646.8
The remainder is 6 after subtracting 664 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
83 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 6646.8
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
83 can be fit into 600 7 times, resulting in a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 6646.807
The remainder is 19 after subtracting 581 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 10:
83 goes into 190 2 times with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 6646.8072
Deduct 166 from 190 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
The number 83 fits into 240 2 times, leaving a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 6646.80722
Subtracting 166 from 240 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The quotient of the division is 6646.80722, and the remainder is 7.4e-05.
