Let's divide 356994 by 79
The aim is to understand the frequency of 79 in 356994.

Step 1:
When dividing 3 by 79, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 79

Going ahead to step 2:
If we divide 35 by 79, we get 0 and a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Grab the next digit (6) from the dividend, add it to 35, then carry on: 356 / 79

Step 3:
When dividing 356 by 79, we get 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 316 from 356, we get 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 79

On to step 4:
409 divided by 79 is 5 with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtract 395 from 409 to get 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 79

Moving on to step 5:
When dividing 149 by 79, we get 1 with a remainder of 70.
Record the quotient 1 as the next digit in the result. 
Result so far: 451.0
Subtracting 79 from 149 leaves us with 70.
Grab the next digit (4) from the dividend, add it to 70, then carry on: 704 / 79

Moving on to step 6:
79 goes into 704 8 times with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 4518.0
Subtract 632 from 704 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 7:
The number 79 fits into 720 9 times, leaving a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 4518.9
Subtracting 711 from 720 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 8:
79 goes into 90 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 4518.91
Subtract 79 from 90 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
79 goes into 110 1 times with a remainder of 31.
The next digit of our result is 1. 
Result so far: 4518.911
The remainder is 31 after subtracting 79 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final outcome is 4518.911, with a leftover of 0.0031.
