78601274 ÷ 579 
Our goal is to divide 78601274 by 579.

Step 1:
7 divided by 579 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 579

Going ahead to step 2:
If we divide 78 by 579, we get 0 and a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 579

Going ahead to step 3:
If we divide 786 by 579, we get 1 and a remainder of 207.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 579 from 786 and we're left with 207.
Fetch the next digit (0) from the dividend, attach it to 207 and continue: 2070 / 579

On to step 4:
2070 divided by 579 is 3 with a remainder of 333.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 1737 from 2070 to get 333.
Include the next digit (1) from the dividend after 333, then repeat: 3331 / 579

Step 5:
When dividing 3331 by 579, we get 5 with a remainder of 436.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
Subtracting 2895 from 3331 leaves us with 436.
Bring next digit (2) of the dividend behind the 436 and repeat the process: 4362 / 579

On to step 6:
When dividing 4362 by 579, we get 7 with a remainder of 309.
The number 7 becomes the next digit in our result. 
Result so far: 1357.0
Subtract 4053 from 4362 to get 309.
Grab the next digit (7) from the dividend, add it to 309, then carry on: 3097 / 579

Moving on to step 7:
3097 divided by 579 is 5 with a remainder of 202.
Write down 5 as next digit of the result. 
Result so far: 13575.0
The remainder is 202 after subtracting 2895 from 3097.
Include the next digit (4) from the dividend after 202, then repeat: 2024 / 579

Advancing to step 8:
If we divide 2024 by 579, we get 3 and a remainder of 287.
Use 3 as the next digit of our solution. 
Result so far: 135753.0
Subtract 1737 from 2024 to get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

On to step 9:
579 goes into 2870 4 times with a remainder of 554.
The number 4 becomes the next digit in our result. 
Result so far: 135753.4
If we take 2316 away from 2870, we end up with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Step 10:
The number 579 fits into 5540 9 times, leaving a remainder of 329.
Put 9 as the next digit of the answer. 
Result so far: 135753.49
Subtract 5211 from 5540 to get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Let's proceed to step 11:
When dividing 3290 by 579, we get 5 with a remainder of 395.
Put 5 as the next digit of the answer. 
Result so far: 135753.495
If we take 2895 away from 3290, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Moving on to step 12:
The number 579 fits into 3950 6 times, leaving a remainder of 476.
Put 6 as the next digit of the answer. 
Result so far: 135753.4956
If we take 3474 away from 3950, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 13:
The number 579 fits into 4760 8 times, leaving a remainder of 128.
Put 8 as the next digit of the answer. 
Result so far: 135753.49568
Subtracting 4632 from 4760 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 14:
If we divide 1280 by 579, we get 2 and a remainder of 122.
Put 2 as the next digit of the answer. 
Result so far: 135753.495682
Deduct 1158 from 1280 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 15:
If we divide 1220 by 579, we get 2 and a remainder of 62.
The next digit of our result is 2. 
Result so far: 135753.4956822
Deduct 1158 from 1220 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Our division results in 135753.4956822 with a remaining 6.2e-07.
