86740648 ÷ 79 
The aim is to understand the frequency of 79 in 86740648.

Moving on to step 1:
8 divided by 79 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 79

On to step 2:
The number 79 fits into 86 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 79 from 86 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 79

Let's proceed to step 3:
79 goes into 77 0 times with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 77, we get 77.
Include the next digit (4) from the dividend after 77, then repeat: 774 / 79

Moving on to step 4:
79 goes into 774 9 times with a remainder of 63.
The next digit of our result is 9. 
Result so far: 109.0
Deduct 711 from 774 and we're left with 63.
Take the next digit (0) from the dividend and append it to 63, then repeat: 630 / 79

Let's proceed to step 5:
The number 79 fits into 630 7 times, leaving a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 1097.0
Deduct 553 from 630 and we're left with 77.
Include the next digit (6) from the dividend after 77, then repeat: 776 / 79

Moving on to step 6:
79 can be fit into 776 9 times, resulting in a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 10979.0
The remainder is 65 after subtracting 711 from 776.
Append the next digit (4) from the dividend to 65 and continue with: 654 / 79

Moving on to step 7:
The number 79 fits into 654 8 times, leaving a remainder of 22.
The next digit of our result is 8. 
Result so far: 109798.0
If we take 632 away from 654, we end up with 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 79

Let's proceed to step 8:
79 can be fit into 228 2 times, resulting in a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 1097982.0
Subtract 158 from 228 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
700 divided by 79 is 8 with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 1097982.8
Deduct 632 from 700 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 10:
680 divided by 79 is 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 1097982.88
If we take 632 away from 680, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 1097982.88, and the remainder is 0.048.
