We look at the division of 83431074 by 771 
We want to divide 83431074 by 771.

Let's proceed to step 1:
771 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 771

On to step 2:
771 can be fit into 83 0 times, resulting in a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Bring next digit (4) of the dividend behind the 83 and repeat the process: 834 / 771

Let's proceed to step 3:
If we divide 834 by 771, we get 1 and a remainder of 63.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 771 from 834 to get 63.
Append the next digit (3) from the dividend to 63 and continue with: 633 / 771

Step 4:
The number 771 fits into 633 0 times, leaving a remainder of 633.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 633, we get 633.
Fetch the next digit (1) from the dividend, attach it to 633 and continue: 6331 / 771

Advancing to step 5:
771 goes into 6331 8 times with a remainder of 163.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
If we subtract 6168 from 6331, we get 163.
Append the next digit (0) from the dividend to 163 and continue with: 1630 / 771

Going ahead to step 6:
771 goes into 1630 2 times with a remainder of 88.
Use 2 as the next digit of our solution. 
Result so far: 1082.0
Deduct 1542 from 1630 and we're left with 88.
Include the next digit (7) from the dividend after 88, then repeat: 887 / 771

Moving on to step 7:
771 goes into 887 1 times with a remainder of 116.
Put 1 as the next digit of the answer. 
Result so far: 10821.0
Subtract 771 from 887 to get 116.
Fetch the next digit (4) from the dividend, attach it to 116 and continue: 1164 / 771

Let's proceed to step 8:
When dividing 1164 by 771, we get 1 with a remainder of 393.
Record the quotient 1 as the next digit in the result. 
Result so far: 108211.0
Deduct 771 from 1164 and we're left with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Going ahead to step 9:
The number 771 fits into 3930 5 times, leaving a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 108211.5
If we take 3855 away from 3930, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 10:
771 can be fit into 750 0 times, resulting in a remainder of 750.
Use 0 as the next digit of our solution. 
Result so far: 108211.5
Subtract 0 from 750 to get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Advancing to step 11:
771 goes into 7500 9 times with a remainder of 561.
Write down 9 as next digit of the result. 
Result so far: 108211.509
Subtract 6939 from 7500 to get 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Moving on to step 12:
The number 771 fits into 5610 7 times, leaving a remainder of 213.
Record the quotient 7 as the next digit in the result. 
Result so far: 108211.5097
If we subtract 5397 from 5610, we get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Going ahead to step 13:
771 can be fit into 2130 2 times, resulting in a remainder of 588.
Record the quotient 2 as the next digit in the result. 
Result so far: 108211.50972
Deduct 1542 from 2130 and we're left 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.

Step 14:
5880 divided by 771 is 7 with a remainder of 483.
Record the quotient 7 as the next digit in the result. 
Result so far: 108211.509727
If we subtract 5397 from 5880, we get 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Let's proceed to step 15:
771 can be fit into 4830 6 times, resulting in a remainder of 204.
The next digit of our result is 6. 
Result so far: 108211.5097276
Deduct 4626 from 4830 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 16:
If we divide 2040 by 771, we get 2 and a remainder of 498.
The next digit of our result is 2. 
Result so far: 108211.50972762
Subtracting 1542 from 2040 leaves us with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

The final result is 108211.50972762 with a remainder of 4.98e-07.
