We look at the division of 77514543 by 79 
We want to divide 77514543 by 79.

Going ahead to step 1:
The number 79 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 79

Moving on to step 2:
The number 79 fits into 77 0 times, leaving a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Bring next digit (5) of the dividend behind the 77 and repeat the process: 775 / 79

Step 3:
79 goes into 775 9 times with a remainder of 64.
The next digit of our result is 9. 
Result so far: 9.0
If we take 711 away from 775, we end up with 64.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 79

Advancing to step 4:
641 divided by 79 is 8 with a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Subtracting 632 from 641 leaves us with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 79

Going ahead to step 5:
94 divided by 79 is 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 981.0
If we subtract 79 from 94, we get 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 79

Let's proceed to step 6:
When dividing 155 by 79, we get 1 with a remainder of 76.
The next digit of our result is 1. 
Result so far: 9811.0
Deduct 79 from 155 and we're left with 76.
Append the next digit (4) from the dividend to 76 and continue with: 764 / 79

Let's proceed to step 7:
If we divide 764 by 79, we get 9 and a remainder of 53.
Use 9 as the next digit of our solution. 
Result so far: 98119.0
Subtract 711 from 764 to get 53.
Bring next digit (3) of the dividend behind the 53 and repeat the process: 533 / 79

On to step 8:
533 divided by 79 is 6 with a remainder of 59.
Use 6 as the next digit of our solution. 
Result so far: 981196.0
Deduct 474 from 533 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 9:
If we divide 590 by 79, we get 7 and a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 981196.7
The remainder is 37 after subtracting 553 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 10:
79 can be fit into 370 4 times, resulting in a remainder of 54.
The next digit of our result is 4. 
Result so far: 981196.74
The remainder is 54 after subtracting 316 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 11:
When dividing 540 by 79, we get 6 with a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 981196.746
The remainder is 66 after subtracting 474 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 12:
The number 79 fits into 660 8 times, leaving a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 981196.7468
If we take 632 away from 660, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
If we divide 280 by 79, we get 3 and a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 981196.74683
If we take 237 away from 280, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 14:
If we divide 430 by 79, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 981196.746835
The remainder is 35 after subtracting 395 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 15:
350 divided by 79 is 4 with a remainder of 34.
The next digit of our result is 4. 
Result so far: 981196.7468354
If we subtract 316 from 350, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 16:
If we divide 340 by 79, we get 4 and a remainder of 24.
The next digit of our result is 4. 
Result so far: 981196.74683544
If we subtract 316 from 340, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 981196.74683544, with a leftover of 2.4e-08.
