99274394 ÷ 980 
We want to figure out the number of times 99274394 can be divided by 980.

Going ahead to step 1:
The number 980 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 980

Step 2:
99 divided by 980 is 0 with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Grab the next digit (2) from the dividend, add it to 99, then carry on: 992 / 980

Step 3:
If we divide 992 by 980, we get 1 and a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 12 after subtracting 980 from 992.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 980

Advancing to step 4:
If we divide 127 by 980, we get 0 and a remainder of 127.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 127, we end up with 127.
Grab the next digit (4) from the dividend, add it to 127, then carry on: 1274 / 980

On to step 5:
980 can be fit into 1274 1 times, resulting in a remainder of 294.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
The remainder is 294 after subtracting 980 from 1274.
Append the next digit (3) from the dividend to 294 and continue with: 2943 / 980

Step 6:
If we divide 2943 by 980, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 1013.0
Deduct 2940 from 2943 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 980

Step 7:
If we divide 39 by 980, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 10130.0
Subtract 0 from 39 to get 39.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 980

On to step 8:
The number 980 fits into 394 0 times, leaving a remainder of 394.
The number 0 becomes the next digit in our result. 
Result so far: 101300.0
The remainder is 394 after subtracting 0 from 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Advancing to step 9:
3940 divided by 980 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 101300.4
Subtract 3920 from 3940 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
980 can be fit into 200 0 times, resulting in a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 101300.4
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 11:
980 goes into 2000 2 times with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 101300.402
The remainder is 40 after subtracting 1960 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
980 can be fit into 400 0 times, resulting in a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 101300.402
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
The number 980 fits into 4000 4 times, leaving a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 101300.40204
If we take 3920 away from 4000, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
If we divide 800 by 980, we get 0 and a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 101300.40204
Subtract 0 from 800 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 15:
980 can be fit into 8000 8 times, resulting in a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 101300.4020408
Subtracting 7840 from 8000 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 16:
The number 980 fits into 1600 1 times, leaving a remainder of 620.
The number 1 becomes the next digit in our result. 
Result so far: 101300.40204081
Deduct 980 from 1600 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

The final result is 101300.40204081 with a remainder of 6.2e-07.
