Let's divide 870843 by 79
The aim is to understand the frequency of 79 in 870843.

On to step 1:
The number 79 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 79

Moving on to step 2:
When dividing 87 by 79, we get 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 8 after subtracting 79 from 87.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 79

Let's proceed to step 3:
80 divided by 79 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 79 away from 80, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 79

Advancing to step 4:
The number 79 fits into 18 0 times, leaving a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 79

Going ahead to step 5:
The number 79 fits into 184 2 times, leaving a remainder of 26.
The next digit of our result is 2. 
Result so far: 1102.0
If we take 158 away from 184, we end up with 26.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 79

Moving on to step 6:
If we divide 263 by 79, we get 3 and a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 11023.0
Subtracting 237 from 263 leaves us 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.

Step 7:
The number 79 fits into 260 3 times, leaving a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 11023.3
The remainder is 23 after subtracting 237 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 8:
79 goes into 230 2 times with a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 11023.32
Subtracting 158 from 230 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 9:
720 divided by 79 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 11023.329
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.

On to step 10:
90 divided by 79 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 11023.3291
Subtracting 79 from 90 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 11:
110 divided by 79 is 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 11023.32911
If we take 79 away from 110, we end up with 31.
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 result is 11023.32911 with a remainder of 3.1e-05.
