We're dividing 77983920 by 763 
We want to divide 77983920 by 763.

On to step 1:
The number 763 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 763

Advancing to step 2:
The number 763 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Fetch the next digit (9) from the dividend, attach it to 77 and continue: 779 / 763

Step 3:
763 goes into 779 1 times with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 763 from 779, we get 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 763

Let's proceed to step 4:
If we divide 168 by 763, we get 0 and a remainder of 168.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 168 and we're left with 168.
Fetch the next digit (3) from the dividend, attach it to 168 and continue: 1683 / 763

Step 5:
The number 763 fits into 1683 2 times, leaving a remainder of 157.
The next digit of our result is 2. 
Result so far: 102.0
If we take 1526 away from 1683, we end up with 157.
Append the next digit (9) from the dividend to 157 and continue with: 1579 / 763

On to step 6:
763 can be fit into 1579 2 times, resulting in a remainder of 53.
Use 2 as the next digit of our solution. 
Result so far: 1022.0
The remainder is 53 after subtracting 1526 from 1579.
Bring next digit (2) of the dividend behind the 53 and repeat the process: 532 / 763

Moving on to step 7:
The number 763 fits into 532 0 times, leaving a remainder of 532.
Record the quotient 0 as the next digit in the result. 
Result so far: 10220.0
Subtract 0 from 532 to get 532.
Append the next digit (0) from the dividend to 532 and continue with: 5320 / 763

Advancing to step 8:
The number 763 fits into 5320 6 times, leaving a remainder of 742.
Write down 6 as next digit of the result. 
Result so far: 102206.0
Subtracting 4578 from 5320 leaves us with 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

On to step 9:
If we divide 7420 by 763, we get 9 and a remainder of 553.
Use 9 as the next digit of our solution. 
Result so far: 102206.9
If we subtract 6867 from 7420, we get 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Let's proceed to step 10:
763 can be fit into 5530 7 times, resulting in a remainder of 189.
Record the quotient 7 as the next digit in the result. 
Result so far: 102206.97
Deduct 5341 from 5530 and we're left with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Let's proceed to step 11:
When dividing 1890 by 763, we get 2 with a remainder of 364.
Record the quotient 2 as the next digit in the result. 
Result so far: 102206.972
The remainder is 364 after subtracting 1526 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Let's proceed to step 12:
763 goes into 3640 4 times with a remainder of 588.
Record the quotient 4 as the next digit in the result. 
Result so far: 102206.9724
Subtracting 3052 from 3640 leaves us with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Let's proceed to step 13:
The number 763 fits into 5880 7 times, leaving a remainder of 539.
The next digit of our result is 7. 
Result so far: 102206.97247
Deduct 5341 from 5880 and we're left with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Step 14:
5390 divided by 763 is 7 with a remainder of 49.
Write down 7 as next digit of the result. 
Result so far: 102206.972477
If we take 5341 away from 5390, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

In conclusion, the division gives 102206.972477 with a balance of 4.9e-06.
