Let's divide 86376122 by 791
The aim is to understand the frequency of 791 in 86376122.

Let's proceed to step 1:
If we divide 8 by 791, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 791

Moving on to step 2:
If we divide 86 by 791, we get 0 and a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Append the next digit (3) from the dividend to 86 and continue with: 863 / 791

Advancing to step 3:
If we divide 863 by 791, we get 1 and a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 791 from 863 leaves us with 72.
Fetch the next digit (7) from the dividend, attach it to 72 and continue: 727 / 791

On to step 4:
If we divide 727 by 791, we get 0 and a remainder of 727.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 727 after subtracting 0 from 727.
Grab the next digit (6) from the dividend, add it to 727, then carry on: 7276 / 791

Moving on to step 5:
791 can be fit into 7276 9 times, resulting in a remainder of 157.
The next digit of our result is 9. 
Result so far: 109.0
Deduct 7119 from 7276 and we're left with 157.
Grab the next digit (1) from the dividend, add it to 157, then carry on: 1571 / 791

On to step 6:
The number 791 fits into 1571 1 times, leaving a remainder of 780.
Write down 1 as next digit of the result. 
Result so far: 1091.0
If we take 791 away from 1571, we end up with 780.
Fetch the next digit (2) from the dividend, attach it to 780 and continue: 7802 / 791

Advancing to step 7:
791 goes into 7802 9 times with a remainder of 683.
Write down 9 as next digit of the result. 
Result so far: 10919.0
Subtracting 7119 from 7802 leaves us with 683.
Bring next digit (2) of the dividend behind the 683 and repeat the process: 6832 / 791

Advancing to step 8:
6832 divided by 791 is 8 with a remainder of 504.
The number 8 becomes the next digit in our result. 
Result so far: 109198.0
Deduct 6328 from 6832 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Let's proceed to step 9:
If we divide 5040 by 791, we get 6 and a remainder of 294.
Use 6 as the next digit of our solution. 
Result so far: 109198.6
If we subtract 4746 from 5040, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 10:
2940 divided by 791 is 3 with a remainder of 567.
Put 3 as the next digit of the answer. 
Result so far: 109198.63
If we take 2373 away from 2940, we end up with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Advancing to step 11:
When dividing 5670 by 791, we get 7 with a remainder of 133.
The number 7 becomes the next digit in our result. 
Result so far: 109198.637
The remainder is 133 after subtracting 5537 from 5670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 12:
When dividing 1330 by 791, we get 1 with a remainder of 539.
The next digit of our result is 1. 
Result so far: 109198.6371
If we take 791 away from 1330, we end up with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Advancing to step 13:
791 goes into 5390 6 times with a remainder of 644.
The next digit of our result is 6. 
Result so far: 109198.63716
If we take 4746 away from 5390, we end up with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Going ahead to step 14:
791 can be fit into 6440 8 times, resulting in a remainder of 112.
The number 8 becomes the next digit in our result. 
Result so far: 109198.637168
If we take 6328 away from 6440, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 15:
791 goes into 1120 1 times with a remainder of 329.
Put 1 as the next digit of the answer. 
Result so far: 109198.6371681
Subtracting 791 from 1120 leaves us with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Advancing to step 16:
When dividing 3290 by 791, we get 4 with a remainder of 126.
Put 4 as the next digit of the answer. 
Result so far: 109198.63716814
Subtract 3164 from 3290 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

The final outcome is 109198.63716814, with a leftover of 1.26e-07.
