We're dividing 77398901 by 787 
Our goal is to divide 77398901 by 787.

On to step 1:
787 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 787

On to step 2:
787 goes into 77 0 times with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Bring next digit (3) of the dividend behind the 77 and repeat the process: 773 / 787

Advancing to step 3:
773 divided by 787 is 0 with a remainder of 773.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 773, we end up with 773.
Fetch the next digit (9) from the dividend, attach it to 773 and continue: 7739 / 787

Going ahead to step 4:
7739 divided by 787 is 9 with a remainder of 656.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 656 after subtracting 7083 from 7739.
Grab the next digit (8) from the dividend, add it to 656, then carry on: 6568 / 787

On to step 5:
When dividing 6568 by 787, we get 8 with a remainder of 272.
Use 8 as the next digit of our solution. 
Result so far: 98.0
Subtract 6296 from 6568 to get 272.
Bring next digit (9) of the dividend behind the 272 and repeat the process: 2729 / 787

Moving on to step 6:
When dividing 2729 by 787, we get 3 with a remainder of 368.
Write down 3 as next digit of the result. 
Result so far: 983.0
The remainder is 368 after subtracting 2361 from 2729.
Append the next digit (0) from the dividend to 368 and continue with: 3680 / 787

Advancing to step 7:
The number 787 fits into 3680 4 times, leaving a remainder of 532.
Record the quotient 4 as the next digit in the result. 
Result so far: 9834.0
The remainder is 532 after subtracting 3148 from 3680.
Append the next digit (1) from the dividend to 532 and continue with: 5321 / 787

Advancing to step 8:
787 goes into 5321 6 times with a remainder of 599.
Write down 6 as next digit of the result. 
Result so far: 98346.0
Subtract 4722 from 5321 to get 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Moving on to step 9:
If we divide 5990 by 787, we get 7 and a remainder of 481.
The number 7 becomes the next digit in our result. 
Result so far: 98346.7
Subtracting 5509 from 5990 leaves us with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Going ahead to step 10:
If we divide 4810 by 787, we get 6 and a remainder of 88.
Record the quotient 6 as the next digit in the result. 
Result so far: 98346.76
If we take 4722 away from 4810, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 11:
787 goes into 880 1 times with a remainder of 93.
Use 1 as the next digit of our solution. 
Result so far: 98346.761
Subtracting 787 from 880 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 12:
787 can be fit into 930 1 times, resulting in a remainder of 143.
Use 1 as the next digit of our solution. 
Result so far: 98346.7611
If we take 787 away from 930, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

In conclusion, the division gives 98346.7611 with a balance of 0.00143.
