Let's divide 77291018 by 850
Let's see how many times 850 fits into 77291018.

On to step 1:
When dividing 7 by 850, we get 0 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.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 850

Step 2:
850 can be fit into 77 0 times, resulting in a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Bring next digit (2) of the dividend behind the 77 and repeat the process: 772 / 850

Going ahead to step 3:
850 goes into 772 0 times with a remainder of 772.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 772 to get 772.
Take the next digit (9) from the dividend and append it to 772, then repeat: 7729 / 850

On to step 4:
When dividing 7729 by 850, we get 9 with a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 7650 from 7729 leaves us with 79.
Append the next digit (1) from the dividend to 79 and continue with: 791 / 850

Advancing to step 5:
850 goes into 791 0 times with a remainder of 791.
Write down 0 as next digit of the result. 
Result so far: 90.0
Subtract 0 from 791 to get 791.
Include the next digit (0) from the dividend after 791, then repeat: 7910 / 850

Going ahead to step 6:
The number 850 fits into 7910 9 times, leaving a remainder of 260.
Write down 9 as next digit of the result. 
Result so far: 909.0
Deduct 7650 from 7910 and we're left with 260.
Grab the next digit (1) from the dividend, add it to 260, then carry on: 2601 / 850

Going ahead to step 7:
850 can be fit into 2601 3 times, resulting in a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 9093.0
Subtract 2550 from 2601 to get 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 850

On to step 8:
850 can be fit into 518 0 times, resulting in a remainder of 518.
Write down 0 as next digit of the result. 
Result so far: 90930.0
If we subtract 0 from 518, we get 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Going ahead to step 9:
850 goes into 5180 6 times with a remainder of 80.
The next digit of our result is 6. 
Result so far: 90930.6
Deduct 5100 from 5180 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
800 divided by 850 is 0 with a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 90930.6
Deduct 0 from 800 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Let's proceed to step 11:
When dividing 8000 by 850, we get 9 with a remainder of 350.
Record the quotient 9 as the next digit in the result. 
Result so far: 90930.609
If we take 7650 away from 8000, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 12:
If we divide 3500 by 850, we get 4 and a remainder of 100.
Write down 4 as next digit of the result. 
Result so far: 90930.6094
Subtracting 3400 from 3500 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 13:
1000 divided by 850 is 1 with a remainder of 150.
Record the quotient 1 as the next digit in the result. 
Result so far: 90930.60941
Subtracting 850 from 1000 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 14:
If we divide 1500 by 850, we get 1 and a remainder of 650.
Write down 1 as next digit of the result. 
Result so far: 90930.609411
If we subtract 850 from 1500, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

The final result is 90930.609411 with a remainder of 6.5e-05.
