We're dividing 77630264 by 850 
We want to divide 77630264 by 850.

Let's proceed to step 1:
850 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 850

Going ahead to step 2:
When dividing 77 by 850, we get 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Fetch the next digit (6) from the dividend, attach it to 77 and continue: 776 / 850

Going ahead to step 3:
850 goes into 776 0 times with a remainder of 776.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 776, we end up with 776.
Include the next digit (3) from the dividend after 776, then repeat: 7763 / 850

Going ahead to step 4:
850 goes into 7763 9 times with a remainder of 113.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 7650 from 7763 to get 113.
Bring next digit (0) of the dividend behind the 113 and repeat the process: 1130 / 850

Advancing to step 5:
850 can be fit into 1130 1 times, resulting in a remainder of 280.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
If we take 850 away from 1130, we end up with 280.
Fetch the next digit (2) from the dividend, attach it to 280 and continue: 2802 / 850

Going ahead to step 6:
850 can be fit into 2802 3 times, resulting in a remainder of 252.
Use 3 as the next digit of our solution. 
Result so far: 913.0
Subtracting 2550 from 2802 leaves us with 252.
Bring next digit (6) of the dividend behind the 252 and repeat the process: 2526 / 850

On to step 7:
850 goes into 2526 2 times with a remainder of 826.
The number 2 becomes the next digit in our result. 
Result so far: 9132.0
The remainder is 826 after subtracting 1700 from 2526.
Bring next digit (4) of the dividend behind the 826 and repeat the process: 8264 / 850

Moving on to step 8:
850 can be fit into 8264 9 times, resulting in a remainder of 614.
Put 9 as the next digit of the answer. 
Result so far: 91329.0
If we take 7650 away from 8264, we end up with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Advancing to step 9:
850 goes into 6140 7 times with a remainder of 190.
Record the quotient 7 as the next digit in the result. 
Result so far: 91329.7
Subtract 5950 from 6140 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 10:
850 can be fit into 1900 2 times, resulting in a remainder of 200.
The next digit of our result is 2. 
Result so far: 91329.72
Subtract 1700 from 1900 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
When dividing 2000 by 850, we get 2 with a remainder of 300.
Write down 2 as next digit of the result. 
Result so far: 91329.722
If we take 1700 away from 2000, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 91329.722, with a leftover of 0.03.
