We look at the division of 917950 by 79 
The aim is to understand the frequency of 79 in 917950.

Let's proceed to step 1:
79 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 79

Advancing to step 2:
79 goes into 91 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 79 from 91 leaves us with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 79

Let's proceed to step 3:
127 divided by 79 is 1 with a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 48 after subtracting 79 from 127.
Append the next digit (9) from the dividend to 48 and continue with: 489 / 79

Let's proceed to step 4:
When dividing 489 by 79, we get 6 with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 116.0
Subtract 474 from 489 to get 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 79

Step 5:
155 divided by 79 is 1 with a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 1161.0
Subtract 79 from 155 to get 76.
Append the next digit (0) from the dividend to 76 and continue with: 760 / 79

Advancing to step 6:
760 divided by 79 is 9 with a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 11619.0
Subtract 711 from 760 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
79 goes into 490 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 11619.6
The remainder is 16 after subtracting 474 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
79 goes into 160 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 11619.62
Subtract 158 from 160 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
When dividing 20 by 79, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 11619.62
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
When dividing 200 by 79, we get 2 with a remainder of 42.
The next digit of our result is 2. 
Result so far: 11619.6202
Subtract 158 from 200 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
79 can be fit into 420 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 11619.62025
Subtracting 395 from 420 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 12:
79 can be fit into 250 3 times, resulting in a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 11619.620253
If we take 237 away from 250, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 13:
79 can be fit into 130 1 times, resulting in a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 11619.6202531
Subtracting 79 from 130 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 14:
79 goes into 510 6 times with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 11619.62025316
Subtract 474 from 510 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 11619.62025316 and a remainder of 3.6e-08.
