We look at the division of 603670 by 79 
The aim is to understand the frequency of 79 in 603670.

Advancing to step 1:
When dividing 6 by 79, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 79

Going ahead to step 2:
If we divide 60 by 79, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 60, we get 60.
Include the next digit (3) from the dividend after 60, then repeat: 603 / 79

Going ahead to step 3:
79 can be fit into 603 7 times, resulting in a remainder of 50.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 553 away from 603, we end up with 50.
Append the next digit (6) from the dividend to 50 and continue with: 506 / 79

Let's proceed to step 4:
79 can be fit into 506 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 76.0
If we take 474 away from 506, we end up with 32.
Include the next digit (7) from the dividend after 32, then repeat: 327 / 79

On to step 5:
If we divide 327 by 79, we get 4 and a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 764.0
If we subtract 316 from 327, we get 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 79

Moving on to step 6:
79 goes into 110 1 times with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 7641.0
If we subtract 79 from 110, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
The number 79 fits into 310 3 times, leaving a remainder of 73.
The next digit of our result is 3. 
Result so far: 7641.3
Deduct 237 from 310 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 8:
The number 79 fits into 730 9 times, leaving a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 7641.39
Subtracting 711 from 730 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
190 divided by 79 is 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 7641.392
Subtracting 158 from 190 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
The number 79 fits into 320 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 7641.3924
If we take 316 away from 320, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
The number 79 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 7641.3924
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
The number 79 fits into 400 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 7641.392405
Subtracting 395 from 400 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
79 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 7641.392405
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
If we divide 500 by 79, we get 6 and a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 7641.39240506
Deduct 474 from 500 and we're left 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.

The final outcome is 7641.39240506, with a leftover of 2.6e-08.
