We look at the division of 875493 by 79 
The aim is to understand the frequency of 79 in 875493.

Moving on to step 1:
8 divided by 79 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 79

Going ahead to step 2:
If we divide 87 by 79, we get 1 and a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 79 away from 87, we end up with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 79

Step 3:
79 can be fit into 85 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 79 away from 85, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 79

On to step 4:
79 goes into 64 0 times with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 110.0
Deduct 0 from 64 and we're left with 64.
Grab the next digit (9) from the dividend, add it to 64, then carry on: 649 / 79

On to step 5:
If we divide 649 by 79, we get 8 and a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 1108.0
If we take 632 away from 649, we end up with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 79

Moving on to step 6:
173 divided by 79 is 2 with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 11082.0
If we take 158 away from 173, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
The number 79 fits into 150 1 times, leaving a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 11082.1
Deduct 79 from 150 and we're left 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 8:
79 goes into 710 8 times with a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 11082.18
Subtract 632 from 710 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 9:
When dividing 780 by 79, we get 9 with a remainder of 69.
The next digit of our result is 9. 
Result so far: 11082.189
If we take 711 away from 780, we end up 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 10:
690 divided by 79 is 8 with a remainder of 58.
The next digit of our result is 8. 
Result so far: 11082.1898
If we subtract 632 from 690, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 11:
The number 79 fits into 580 7 times, leaving a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 11082.18987
Subtracting 553 from 580 leaves us 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.

On to step 12:
270 divided by 79 is 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 11082.189873
The remainder is 33 after subtracting 237 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 13:
The number 79 fits into 330 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 11082.1898734
If we take 316 away from 330, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
140 divided by 79 is 1 with a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 11082.18987341
The remainder is 61 after subtracting 79 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

After the division, we end up with 11082.18987341 and a remainder of 6.1e-08.
