We divide 998574 by 79
Our goal is to divide 998574 by 79.

Step 1:
If we divide 9 by 79, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 79

On to step 2:
79 can be fit into 99 1 times, resulting in a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 20 after subtracting 79 from 99.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 79

Advancing to step 3:
79 can be fit into 208 2 times, resulting in a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 158 from 208 leaves us with 50.
Include the next digit (5) from the dividend after 50, then repeat: 505 / 79

On to step 4:
79 can be fit into 505 6 times, resulting in a remainder of 31.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Deduct 474 from 505 and we're left with 31.
Include the next digit (7) from the dividend after 31, then repeat: 317 / 79

Let's proceed to step 5:
79 can be fit into 317 4 times, resulting in a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 1264.0
Subtract 316 from 317 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 79

On to step 6:
The number 79 fits into 14 0 times, leaving a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 12640.0
Subtracting 0 from 14 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
The number 79 fits into 140 1 times, leaving a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 12640.1
If we take 79 away from 140, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 8:
If we divide 610 by 79, we get 7 and a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 12640.17
Deduct 553 from 610 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 9:
When dividing 570 by 79, we get 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 12640.177
If we take 553 away from 570, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 12640.177, with a leftover of 0.0017.
