We divide 991234 by 83
The aim is to understand the frequency of 83 in 991234.

Advancing to step 1:
9 divided by 83 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 83

Step 2:
The number 83 fits into 99 1 times, leaving a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 16 after subtracting 83 from 99.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 83

Moving on to step 3:
The number 83 fits into 161 1 times, leaving a remainder of 78.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 83 from 161 leaves us with 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 83

Moving on to step 4:
83 can be fit into 782 9 times, resulting in a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 119.0
Subtracting 747 from 782 leaves us with 35.
Append the next digit (3) from the dividend to 35 and continue with: 353 / 83

On to step 5:
When dividing 353 by 83, we get 4 with a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 1194.0
If we take 332 away from 353, we end up with 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 83

Advancing to step 6:
83 goes into 214 2 times with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 11942.0
If we subtract 166 from 214, we 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.

On to step 7:
The number 83 fits into 480 5 times, leaving a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 11942.5
Deduct 415 from 480 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 8:
83 can be fit into 650 7 times, resulting in a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 11942.57
Subtracting 581 from 650 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 9:
83 goes into 690 8 times with a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 11942.578
Subtracting 664 from 690 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
83 goes into 260 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 11942.5783
If we subtract 249 from 260, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
110 divided by 83 is 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 11942.57831
Deduct 83 from 110 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 12:
270 divided by 83 is 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 11942.578313
If we subtract 249 from 270, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 13:
83 can be fit into 210 2 times, resulting in a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 11942.5783132
Deduct 166 from 210 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 14:
83 can be fit into 440 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 11942.57831325
The remainder is 25 after subtracting 415 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 11942.57831325 and a remainder of 2.5e-08.
