We're dividing 198778 by 79 
Let's see how many times 79 fits into 198778.

Step 1:
1 divided by 79 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 79

On to step 2:
79 goes into 19 0 times with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 79

Advancing to step 3:
If we divide 198 by 79, we get 2 and a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 158 away from 198, we end up with 40.
Fetch the next digit (7) from the dividend, attach it to 40 and continue: 407 / 79

On to step 4:
79 goes into 407 5 times with a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 395 away from 407, we end up with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 79

Let's proceed to step 5:
The number 79 fits into 127 1 times, leaving a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 251.0
Subtracting 79 from 127 leaves us with 48.
Take the next digit (8) from the dividend and append it to 48, then repeat: 488 / 79

Moving on to step 6:
When dividing 488 by 79, we get 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 2516.0
Subtracting 474 from 488 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:
79 goes into 140 1 times with a remainder of 61.
Write down 1 as next digit of the result. 
Result so far: 2516.1
Subtract 79 from 140 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 8:
The number 79 fits into 610 7 times, leaving a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 2516.17
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:
If we divide 570 by 79, we get 7 and a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 2516.177
Subtract 553 from 570 to get 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 2516.177, with a leftover of 0.0017.
