Let's divide 9877658 by 256
We want to divide 9877658 by 256.

On to step 1:
When dividing 9 by 256, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 256

Advancing to step 2:
98 divided by 256 is 0 with a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Bring next digit (7) of the dividend behind the 98 and repeat the process: 987 / 256

Step 3:
The number 256 fits into 987 3 times, leaving a remainder of 219.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 219 after subtracting 768 from 987.
Grab the next digit (7) from the dividend, add it to 219, then carry on: 2197 / 256

Moving on to step 4:
256 goes into 2197 8 times with a remainder of 149.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Deduct 2048 from 2197 and we're left with 149.
Take the next digit (6) from the dividend and append it to 149, then repeat: 1496 / 256

Going ahead to step 5:
256 goes into 1496 5 times with a remainder of 216.
Record the quotient 5 as the next digit in the result. 
Result so far: 385.0
Deduct 1280 from 1496 and we're left with 216.
Fetch the next digit (5) from the dividend, attach it to 216 and continue: 2165 / 256

Moving on to step 6:
256 goes into 2165 8 times with a remainder of 117.
Write down 8 as next digit of the result. 
Result so far: 3858.0
Deduct 2048 from 2165 and we're left with 117.
Bring next digit (8) of the dividend behind the 117 and repeat the process: 1178 / 256

Moving on to step 7:
256 goes into 1178 4 times with a remainder of 154.
Write down 4 as next digit of the result. 
Result so far: 38584.0
The remainder is 154 after subtracting 1024 from 1178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 8:
256 can be fit into 1540 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 38584.6
Subtracting 1536 from 1540 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
40 divided by 256 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 38584.6
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
The number 256 fits into 400 1 times, leaving a remainder of 144.
Write down 1 as next digit of the result. 
Result so far: 38584.601
Subtract 256 from 400 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 11:
The number 256 fits into 1440 5 times, leaving a remainder of 160.
Write down 5 as next digit of the result. 
Result so far: 38584.6015
If we take 1280 away from 1440, we end up 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.

On to step 12:
256 goes into 1600 6 times with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 38584.60156
If we subtract 1536 from 1600, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
The number 256 fits into 640 2 times, leaving a remainder of 128.
Use 2 as the next digit of our solution. 
Result so far: 38584.601562
If we subtract 512 from 640, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 14:
256 goes into 1280 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 38584.6015625
Subtracting 1280 from 1280 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 15:
0 divided by 256 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 38584.6015625
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 38584.6015625, with a leftover of 0.0.
