We're dividing 642869 by 79 
Our goal is to divide 642869 by 79.

Let's proceed to step 1:
79 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 79

Advancing to step 2:
When dividing 64 by 79, we get 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 79

On to step 3:
79 goes into 642 8 times with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 632 away from 642, we end up with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 79

Let's proceed to step 4:
If we divide 108 by 79, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we take 79 away from 108, we end up with 29.
Include the next digit (6) from the dividend after 29, then repeat: 296 / 79

Let's proceed to step 5:
79 can be fit into 296 3 times, resulting in a remainder of 59.
The number 3 becomes the next digit in our result. 
Result so far: 813.0
If we subtract 237 from 296, we get 59.
Append the next digit (9) from the dividend to 59 and continue with: 599 / 79

Let's proceed to step 6:
When dividing 599 by 79, we get 7 with a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 8137.0
Subtract 553 from 599 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
When dividing 460 by 79, we get 5 with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 8137.5
Deduct 395 from 460 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 8:
When dividing 650 by 79, we get 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 8137.58
Subtract 632 from 650 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
The number 79 fits into 180 2 times, leaving a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 8137.582
Deduct 158 from 180 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
79 goes into 220 2 times with a remainder of 62.
The next digit of our result is 2. 
Result so far: 8137.5822
If we subtract 158 from 220, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The quotient of the division is 8137.5822, and the remainder is 0.00062.
