838458 divided by 83 
The aim is to understand the frequency of 83 in 838458.

Advancing to step 1:
8 divided by 83 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 83

On to step 2:
83 divided by 83 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 83 from 83 to get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 83

Advancing to step 3:
8 divided by 83 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 8 to get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 83

Step 4:
84 divided by 83 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 101.0
If we take 83 away from 84, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 83

Advancing to step 5:
When dividing 15 by 83, we get 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 1010.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 83

Step 6:
The number 83 fits into 158 1 times, leaving a remainder of 75.
Record the quotient 1 as the next digit in the result. 
Result so far: 10101.0
Subtracting 83 from 158 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 7:
83 can be fit into 750 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 10101.9
If we take 747 away from 750, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
The number 83 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 10101.9
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
When dividing 300 by 83, we get 3 with a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 10101.903
If we take 249 away from 300, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 10:
510 divided by 83 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 10101.9036
If we subtract 498 from 510, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
When dividing 120 by 83, we get 1 with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 10101.90361
Deduct 83 from 120 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 12:
83 can be fit into 370 4 times, resulting in a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 10101.903614
If we subtract 332 from 370, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 13:
If we divide 380 by 83, we get 4 and a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 10101.9036144
Subtract 332 from 380 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 10101.9036144, and the remainder is 4.8e-07.
