Let's divide 83990244 by 766
Our goal is to divide 83990244 by 766.

On to step 1:
The number 766 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 766

Step 2:
If we divide 83 by 766, we get 0 and a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Grab the next digit (9) from the dividend, add it to 83, then carry on: 839 / 766

On to step 3:
The number 766 fits into 839 1 times, leaving a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 73 after subtracting 766 from 839.
Include the next digit (9) from the dividend after 73, then repeat: 739 / 766

Going ahead to step 4:
766 can be fit into 739 0 times, resulting in a remainder of 739.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 739 leaves us with 739.
Bring next digit (0) of the dividend behind the 739 and repeat the process: 7390 / 766

Moving on to step 5:
When dividing 7390 by 766, we get 9 with a remainder of 496.
Put 9 as the next digit of the answer. 
Result so far: 109.0
Deduct 6894 from 7390 and we're left with 496.
Fetch the next digit (2) from the dividend, attach it to 496 and continue: 4962 / 766

On to step 6:
When dividing 4962 by 766, we get 6 with a remainder of 366.
The next digit of our result is 6. 
Result so far: 1096.0
If we take 4596 away from 4962, we end up with 366.
Bring next digit (4) of the dividend behind the 366 and repeat the process: 3664 / 766

Moving on to step 7:
3664 divided by 766 is 4 with a remainder of 600.
Record the quotient 4 as the next digit in the result. 
Result so far: 10964.0
If we subtract 3064 from 3664, we get 600.
Append the next digit (4) from the dividend to 600 and continue with: 6004 / 766

Moving on to step 8:
766 can be fit into 6004 7 times, resulting in a remainder of 642.
Use 7 as the next digit of our solution. 
Result so far: 109647.0
If we take 5362 away from 6004, we end up with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

On to step 9:
When dividing 6420 by 766, we get 8 with a remainder of 292.
The next digit of our result is 8. 
Result so far: 109647.8
Subtracting 6128 from 6420 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 10:
If we divide 2920 by 766, we get 3 and a remainder of 622.
The number 3 becomes the next digit in our result. 
Result so far: 109647.83
Subtract 2298 from 2920 to get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

On to step 11:
766 goes into 6220 8 times with a remainder of 92.
The number 8 becomes the next digit in our result. 
Result so far: 109647.838
The remainder is 92 after subtracting 6128 from 6220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 12:
If we divide 920 by 766, we get 1 and a remainder of 154.
Use 1 as the next digit of our solution. 
Result so far: 109647.8381
If we subtract 766 from 920, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 13:
1540 divided by 766 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 109647.83812
Subtracting 1532 from 1540 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
If we divide 80 by 766, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 109647.83812
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 15:
If we divide 800 by 766, we get 1 and a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 109647.8381201
If we take 766 away from 800, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 16:
766 goes into 340 0 times with a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 109647.8381201
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The final outcome is 109647.8381201, with a leftover of 3.4e-07.
