851138 divided by 79 
The aim is to understand the frequency of 79 in 851138.

Moving on to step 1:
If we divide 8 by 79, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 79

On to step 2:
79 can be fit into 85 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 79 away from 85, we end up with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 79

Advancing to step 3:
The number 79 fits into 61 0 times, leaving a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 61, we get 61.
Grab the next digit (1) from the dividend, add it to 61, then carry on: 611 / 79

Going ahead to step 4:
79 goes into 611 7 times with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 107.0
Deduct 553 from 611 and we're left with 58.
Include the next digit (3) from the dividend after 58, then repeat: 583 / 79

Step 5:
When dividing 583 by 79, we get 7 with a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 1077.0
Deduct 553 from 583 and we're left with 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 79

Advancing to step 6:
79 can be fit into 308 3 times, resulting in a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 10773.0
If we take 237 away from 308, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 7:
79 can be fit into 710 8 times, resulting in a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 10773.8
Deduct 632 from 710 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 8:
79 can be fit into 780 9 times, resulting in a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 10773.89
Deduct 711 from 780 and we're left 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.

Moving on to step 9:
79 can be fit into 690 8 times, resulting in a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 10773.898
Deduct 632 from 690 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
The number 79 fits into 580 7 times, leaving a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 10773.8987
If we subtract 553 from 580, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 11:
270 divided by 79 is 3 with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 10773.89873
If we subtract 237 from 270, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 12:
When dividing 330 by 79, we get 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 10773.898734
If we subtract 316 from 330, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
140 divided by 79 is 1 with a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 10773.8987341
Subtracting 79 from 140 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 14:
79 goes into 610 7 times with a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 10773.89873417
If we subtract 553 from 610, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final outcome is 10773.89873417, with a leftover of 5.7e-08.
