We look at the division of 12398295 by 277 
Our goal is to divide 12398295 by 277.

Step 1:
277 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 277

Advancing to step 2:
When dividing 12 by 277, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 277

Step 3:
When dividing 123 by 277, we get 0 with a remainder of 123.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 123 and we're left with 123.
Include the next digit (9) from the dividend after 123, then repeat: 1239 / 277

Going ahead to step 4:
277 can be fit into 1239 4 times, resulting in a remainder of 131.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 1108 from 1239 to get 131.
Include the next digit (8) from the dividend after 131, then repeat: 1318 / 277

Going ahead to step 5:
277 goes into 1318 4 times with a remainder of 210.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
The remainder is 210 after subtracting 1108 from 1318.
Grab the next digit (2) from the dividend, add it to 210, then carry on: 2102 / 277

Let's proceed to step 6:
The number 277 fits into 2102 7 times, leaving a remainder of 163.
Put 7 as the next digit of the answer. 
Result so far: 447.0
Subtract 1939 from 2102 to get 163.
Grab the next digit (9) from the dividend, add it to 163, then carry on: 1639 / 277

Advancing to step 7:
277 can be fit into 1639 5 times, resulting in a remainder of 254.
Use 5 as the next digit of our solution. 
Result so far: 4475.0
If we subtract 1385 from 1639, we get 254.
Append the next digit (5) from the dividend to 254 and continue with: 2545 / 277

Step 8:
The number 277 fits into 2545 9 times, leaving a remainder of 52.
Record the quotient 9 as the next digit in the result. 
Result so far: 44759.0
If we take 2493 away from 2545, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
The number 277 fits into 520 1 times, leaving a remainder of 243.
Record the quotient 1 as the next digit in the result. 
Result so far: 44759.1
Subtract 277 from 520 to get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Going ahead to step 10:
If we divide 2430 by 277, we get 8 and a remainder of 214.
Put 8 as the next digit of the answer. 
Result so far: 44759.18
The remainder is 214 after subtracting 2216 from 2430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 11:
2140 divided by 277 is 7 with a remainder of 201.
The number 7 becomes the next digit in our result. 
Result so far: 44759.187
The remainder is 201 after subtracting 1939 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 12:
2010 divided by 277 is 7 with a remainder of 71.
The next digit of our result is 7. 
Result so far: 44759.1877
If we subtract 1939 from 2010, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The final outcome is 44759.1877, with a leftover of 0.00071.
