We're dividing 793261 by 79 
The aim is to understand the frequency of 79 in 793261.

On to step 1:
The number 79 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 79

Moving on to step 2:
79 goes into 79 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 79 from 79 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 79

Going ahead to step 3:
When dividing 3 by 79, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 3, we end up with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 79

Let's proceed to step 4:
When dividing 32 by 79, we get 0 with a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 100.0
If we take 0 away from 32, we end up with 32.
Bring next digit (6) of the dividend behind the 32 and repeat the process: 326 / 79

Going ahead to step 5:
If we divide 326 by 79, we get 4 and a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 1004.0
If we subtract 316 from 326, we get 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 79

Advancing to step 6:
When dividing 101 by 79, we get 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 10041.0
If we take 79 away from 101, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
79 can be fit into 220 2 times, resulting in a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 10041.2
If we take 158 away from 220, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 8:
If we divide 620 by 79, we get 7 and a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 10041.27
If we take 553 away from 620, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 9:
79 goes into 670 8 times with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 10041.278
The remainder is 38 after subtracting 632 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
The number 79 fits into 380 4 times, leaving a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 10041.2784
Subtracting 316 from 380 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
When dividing 640 by 79, we get 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 10041.27848
If we subtract 632 from 640, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
79 can be fit into 80 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 10041.278481
The remainder is 1 after subtracting 79 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
The number 79 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 10041.278481
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
79 can be fit into 100 1 times, resulting in a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 10041.27848101
If we take 79 away from 100, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 10041.27848101 and a remainder of 2.1e-08.
