Let's divide 83109372 by 811
The aim is to understand the frequency of 811 in 83109372.

Let's proceed to step 1:
The number 811 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 811

Going ahead to step 2:
811 goes into 83 0 times with a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Include the next digit (1) from the dividend after 83, then repeat: 831 / 811

Step 3:
The number 811 fits into 831 1 times, leaving a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 811 from 831, we get 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 811

Let's proceed to step 4:
If we divide 200 by 811, we get 0 and a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 200, we get 200.
Bring next digit (9) of the dividend behind the 200 and repeat the process: 2009 / 811

On to step 5:
811 can be fit into 2009 2 times, resulting in a remainder of 387.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Subtracting 1622 from 2009 leaves us with 387.
Fetch the next digit (3) from the dividend, attach it to 387 and continue: 3873 / 811

On to step 6:
If we divide 3873 by 811, we get 4 and a remainder of 629.
Put 4 as the next digit of the answer. 
Result so far: 1024.0
Subtract 3244 from 3873 to get 629.
Grab the next digit (7) from the dividend, add it to 629, then carry on: 6297 / 811

On to step 7:
6297 divided by 811 is 7 with a remainder of 620.
Use 7 as the next digit of our solution. 
Result so far: 10247.0
If we subtract 5677 from 6297, we get 620.
Grab the next digit (2) from the dividend, add it to 620, then carry on: 6202 / 811

Step 8:
If we divide 6202 by 811, we get 7 and a remainder of 525.
Write down 7 as next digit of the result. 
Result so far: 102477.0
If we subtract 5677 from 6202, we get 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Advancing to step 9:
811 can be fit into 5250 6 times, resulting in a remainder of 384.
Record the quotient 6 as the next digit in the result. 
Result so far: 102477.6
Deduct 4866 from 5250 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 10:
3840 divided by 811 is 4 with a remainder of 596.
Put 4 as the next digit of the answer. 
Result so far: 102477.64
Subtract 3244 from 3840 to get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

On to step 11:
When dividing 5960 by 811, we get 7 with a remainder of 283.
The next digit of our result is 7. 
Result so far: 102477.647
Subtract 5677 from 5960 to get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Advancing to step 12:
When dividing 2830 by 811, we get 3 with a remainder of 397.
Put 3 as the next digit of the answer. 
Result so far: 102477.6473
If we subtract 2433 from 2830, we get 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Step 13:
811 goes into 3970 4 times with a remainder of 726.
Record the quotient 4 as the next digit in the result. 
Result so far: 102477.64734
The remainder is 726 after subtracting 3244 from 3970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Let's proceed to step 14:
When dividing 7260 by 811, we get 8 with a remainder of 772.
The number 8 becomes the next digit in our result. 
Result so far: 102477.647348
Subtracting 6488 from 7260 leaves us with 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Advancing to step 15:
7720 divided by 811 is 9 with a remainder of 421.
The next digit of our result is 9. 
Result so far: 102477.6473489
Deduct 7299 from 7720 and we're left with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Step 16:
811 goes into 4210 5 times with a remainder of 155.
Record the quotient 5 as the next digit in the result. 
Result so far: 102477.64734895
The remainder is 155 after subtracting 4055 from 4210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

The final result is 102477.64734895 with a remainder of 1.55e-07.
