We look at the division of 79380457 by 174 
We want to figure out the number of times 79380457 can be divided by 174.

On to step 1:
If we divide 7 by 174, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 174

Advancing to step 2:
174 can be fit into 79 0 times, resulting in a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Take the next digit (3) from the dividend and append it to 79, then repeat: 793 / 174

On to step 3:
If we divide 793 by 174, we get 4 and a remainder of 97.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 696 from 793, we get 97.
Append the next digit (8) from the dividend to 97 and continue with: 978 / 174

On to step 4:
If we divide 978 by 174, we get 5 and a remainder of 108.
Put 5 as the next digit of the answer. 
Result so far: 45.0
The remainder is 108 after subtracting 870 from 978.
Take the next digit (0) from the dividend and append it to 108, then repeat: 1080 / 174

On to step 5:
174 can be fit into 1080 6 times, resulting in a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 456.0
If we take 1044 away from 1080, we end up with 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 174

Let's proceed to step 6:
The number 174 fits into 364 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 4562.0
The remainder is 16 after subtracting 348 from 364.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 174

Going ahead to step 7:
174 goes into 165 0 times with a remainder of 165.
Put 0 as the next digit of the answer. 
Result so far: 45620.0
The remainder is 165 after subtracting 0 from 165.
Append the next digit (7) from the dividend to 165 and continue with: 1657 / 174

Let's proceed to step 8:
174 can be fit into 1657 9 times, resulting in a remainder of 91.
Write down 9 as next digit of the result. 
Result so far: 456209.0
Subtracting 1566 from 1657 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 9:
910 divided by 174 is 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 456209.5
Deduct 870 from 910 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
When dividing 400 by 174, we get 2 with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 456209.52
Deduct 348 from 400 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
174 goes into 520 2 times with a remainder of 172.
Put 2 as the next digit of the answer. 
Result so far: 456209.522
If we take 348 away from 520, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The final result is 456209.522 with a remainder of 0.0172.
