Let's divide 78971301 by 79
The aim is to understand the frequency of 79 in 78971301.

On to step 1:
79 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 79

Let's proceed to step 2:
When dividing 78 by 79, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Fetch the next digit (9) from the dividend, attach it to 78 and continue: 789 / 79

Moving on to step 3:
79 can be fit into 789 9 times, resulting in a remainder of 78.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 711 from 789 to get 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 79

Moving on to step 4:
If we divide 787 by 79, we get 9 and a remainder of 76.
Write down 9 as next digit of the result. 
Result so far: 99.0
If we take 711 away from 787, we end up with 76.
Grab the next digit (1) from the dividend, add it to 76, then carry on: 761 / 79

Moving on to step 5:
When dividing 761 by 79, we get 9 with a remainder of 50.
The number 9 becomes the next digit in our result. 
Result so far: 999.0
Deduct 711 from 761 and we're left with 50.
Take the next digit (3) from the dividend and append it to 50, then repeat: 503 / 79

Let's proceed to step 6:
When dividing 503 by 79, we get 6 with a remainder of 29.
The next digit of our result is 6. 
Result so far: 9996.0
If we subtract 474 from 503, we get 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 79

Step 7:
290 divided by 79 is 3 with a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 99963.0
If we subtract 237 from 290, we get 53.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 79

Let's proceed to step 8:
531 divided by 79 is 6 with a remainder of 57.
Write down 6 as next digit of the result. 
Result so far: 999636.0
Subtract 474 from 531 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 9:
When dividing 570 by 79, we get 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 999636.7
Deduct 553 from 570 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 10:
The number 79 fits into 170 2 times, leaving a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 999636.72
Subtract 158 from 170 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
79 goes into 120 1 times with a remainder of 41.
The next digit of our result is 1. 
Result so far: 999636.721
If we take 79 away from 120, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 12:
79 can be fit into 410 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 999636.7215
The remainder is 15 after subtracting 395 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 13:
If we divide 150 by 79, we get 1 and a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 999636.72151
The remainder is 71 after subtracting 79 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 14:
If we divide 710 by 79, we get 8 and a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 999636.721518
Deduct 632 from 710 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 15:
79 can be fit into 780 9 times, resulting in a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 999636.7215189
Deduct 711 from 780 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 16:
79 can be fit into 690 8 times, resulting in a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 999636.72151898
If we subtract 632 from 690, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The quotient of the division is 999636.72151898, and the remainder is 5.8e-08.
