98638448 ÷ 782 
Our goal is to divide 98638448 by 782.

On to step 1:
782 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 782

Advancing to step 2:
98 divided by 782 is 0 with a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Bring next digit (6) of the dividend behind the 98 and repeat the process: 986 / 782

On to step 3:
986 divided by 782 is 1 with a remainder of 204.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 782 from 986 leaves us with 204.
Grab the next digit (3) from the dividend, add it to 204, then carry on: 2043 / 782

Advancing to step 4:
782 goes into 2043 2 times with a remainder of 479.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 1564 from 2043, we get 479.
Grab the next digit (8) from the dividend, add it to 479, then carry on: 4798 / 782

Advancing to step 5:
782 goes into 4798 6 times with a remainder of 106.
Put 6 as the next digit of the answer. 
Result so far: 126.0
The remainder is 106 after subtracting 4692 from 4798.
Fetch the next digit (4) from the dividend, attach it to 106 and continue: 1064 / 782

On to step 6:
782 goes into 1064 1 times with a remainder of 282.
The number 1 becomes the next digit in our result. 
Result so far: 1261.0
Subtract 782 from 1064 to get 282.
Include the next digit (4) from the dividend after 282, then repeat: 2824 / 782

Moving on to step 7:
782 goes into 2824 3 times with a remainder of 478.
Record the quotient 3 as the next digit in the result. 
Result so far: 12613.0
If we take 2346 away from 2824, we end up with 478.
Grab the next digit (8) from the dividend, add it to 478, then carry on: 4788 / 782

Going ahead to step 8:
When dividing 4788 by 782, we get 6 with a remainder of 96.
The next digit of our result is 6. 
Result so far: 126136.0
Subtract 4692 from 4788 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 9:
When dividing 960 by 782, we get 1 with a remainder of 178.
Put 1 as the next digit of the answer. 
Result so far: 126136.1
Deduct 782 from 960 and we're left with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 10:
1780 divided by 782 is 2 with a remainder of 216.
The next digit of our result is 2. 
Result so far: 126136.12
Subtracting 1564 from 1780 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 11:
If we divide 2160 by 782, we get 2 and a remainder of 596.
Record the quotient 2 as the next digit in the result. 
Result so far: 126136.122
Subtracting 1564 from 2160 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

The final result is 126136.122 with a remainder of 0.0596.
