We look at the division of 45378274 by 79 
We want to divide 45378274 by 79.

On to step 1:
4 divided by 79 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 79

Advancing to step 2:
If we divide 45 by 79, we get 0 and a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 79

Step 3:
If we divide 453 by 79, we get 5 and a remainder of 58.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 395 from 453 to get 58.
Grab the next digit (7) from the dividend, add it to 58, then carry on: 587 / 79

On to step 4:
587 divided by 79 is 7 with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
Subtracting 553 from 587 leaves us with 34.
Append the next digit (8) from the dividend to 34 and continue with: 348 / 79

Let's proceed to step 5:
348 divided by 79 is 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 574.0
The remainder is 32 after subtracting 316 from 348.
Grab the next digit (2) from the dividend, add it to 32, then carry on: 322 / 79

Moving on to step 6:
If we divide 322 by 79, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 5744.0
Subtracting 316 from 322 leaves us with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 79

Step 7:
79 goes into 67 0 times with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 57440.0
Deduct 0 from 67 and we're left with 67.
Append the next digit (4) from the dividend to 67 and continue with: 674 / 79

Step 8:
674 divided by 79 is 8 with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 574408.0
Subtracting 632 from 674 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
If we divide 420 by 79, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 574408.5
The remainder is 25 after subtracting 395 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
79 can be fit into 250 3 times, resulting in a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 574408.53
If we subtract 237 from 250, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 11:
If we divide 130 by 79, we get 1 and a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 574408.531
The remainder is 51 after subtracting 79 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 12:
79 goes into 510 6 times with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 574408.5316
Subtracting 474 from 510 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
79 goes into 360 4 times with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 574408.53164
If we subtract 316 from 360, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 14:
440 divided by 79 is 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 574408.531645
Deduct 395 from 440 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 15:
79 goes into 450 5 times with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 574408.5316455
The remainder is 55 after subtracting 395 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 574408.5316455 and a remainder of 5.5e-07.
