98712255 ÷ 283 
We want to figure out the number of times 98712255 can be divided by 283.

Going ahead to step 1:
283 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 283

Moving on to step 2:
The number 283 fits into 98 0 times, leaving a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Bring next digit (7) of the dividend behind the 98 and repeat the process: 987 / 283

On to step 3:
283 goes into 987 3 times with a remainder of 138.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 849 away from 987, we end up with 138.
Take the next digit (1) from the dividend and append it to 138, then repeat: 1381 / 283

Step 4:
1381 divided by 283 is 4 with a remainder of 249.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we subtract 1132 from 1381, we get 249.
Take the next digit (2) from the dividend and append it to 249, then repeat: 2492 / 283

Advancing to step 5:
When dividing 2492 by 283, we get 8 with a remainder of 228.
Use 8 as the next digit of our solution. 
Result so far: 348.0
Subtracting 2264 from 2492 leaves us with 228.
Append the next digit (2) from the dividend to 228 and continue with: 2282 / 283

On to step 6:
When dividing 2282 by 283, we get 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 3488.0
The remainder is 18 after subtracting 2264 from 2282.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 283

Going ahead to step 7:
If we divide 185 by 283, we get 0 and a remainder of 185.
Write down 0 as next digit of the result. 
Result so far: 34880.0
Subtract 0 from 185 to get 185.
Grab the next digit (5) from the dividend, add it to 185, then carry on: 1855 / 283

Step 8:
283 goes into 1855 6 times with a remainder of 157.
The next digit of our result is 6. 
Result so far: 348806.0
If we take 1698 away from 1855, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 9:
283 goes into 1570 5 times with a remainder of 155.
Put 5 as the next digit of the answer. 
Result so far: 348806.5
If we subtract 1415 from 1570, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 10:
283 goes into 1550 5 times with a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 348806.55
If we subtract 1415 from 1550, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

The final outcome is 348806.55, with a leftover of 0.135.
