We're dividing 63286121 by 850 
We want to divide 63286121 by 850.

Advancing to step 1:
When dividing 6 by 850, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 850

Going ahead to step 2:
850 goes into 63 0 times with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Grab the next digit (2) from the dividend, add it to 63, then carry on: 632 / 850

Going ahead to step 3:
If we divide 632 by 850, we get 0 and a remainder of 632.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 632 after subtracting 0 from 632.
Grab the next digit (8) from the dividend, add it to 632, then carry on: 6328 / 850

Let's proceed to step 4:
6328 divided by 850 is 7 with a remainder of 378.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 5950 from 6328, we get 378.
Include the next digit (6) from the dividend after 378, then repeat: 3786 / 850

Going ahead to step 5:
3786 divided by 850 is 4 with a remainder of 386.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Deduct 3400 from 3786 and we're left with 386.
Bring next digit (1) of the dividend behind the 386 and repeat the process: 3861 / 850

Going ahead to step 6:
850 goes into 3861 4 times with a remainder of 461.
Record the quotient 4 as the next digit in the result. 
Result so far: 744.0
If we subtract 3400 from 3861, we get 461.
Include the next digit (2) from the dividend after 461, then repeat: 4612 / 850

Advancing to step 7:
850 can be fit into 4612 5 times, resulting in a remainder of 362.
The next digit of our result is 5. 
Result so far: 7445.0
Deduct 4250 from 4612 and we're left with 362.
Bring next digit (1) of the dividend behind the 362 and repeat the process: 3621 / 850

On to step 8:
The number 850 fits into 3621 4 times, leaving a remainder of 221.
Use 4 as the next digit of our solution. 
Result so far: 74454.0
Subtracting 3400 from 3621 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

On to step 9:
850 goes into 2210 2 times with a remainder of 510.
Record the quotient 2 as the next digit in the result. 
Result so far: 74454.2
If we subtract 1700 from 2210, we get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Moving on to step 10:
850 goes into 5100 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 74454.26
If we subtract 5100 from 5100, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
850 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 74454.26
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
850 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 74454.26
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 74454.26 with a remainder of 0.0.
