Let's divide 850071 by 51
We want to figure out the number of times 850071 can be divided by 51.

Step 1:
When dividing 8 by 51, we get 0 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.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 51

On to step 2:
51 goes into 85 1 times with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 51 from 85 and we're left with 34.
Append the next digit (0) from the dividend to 34 and continue with: 340 / 51

Moving on to step 3:
The number 51 fits into 340 6 times, leaving a remainder of 34.
The next digit of our result is 6. 
Result so far: 16.0
If we take 306 away from 340, we end up with 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 51

Moving on to step 4:
When dividing 340 by 51, we get 6 with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 166.0
If we take 306 away from 340, we end up with 34.
Bring next digit (7) of the dividend behind the 34 and repeat the process: 347 / 51

Moving on to step 5:
51 goes into 347 6 times with a remainder of 41.
The next digit of our result is 6. 
Result so far: 1666.0
If we subtract 306 from 347, we get 41.
Bring next digit (1) of the dividend behind the 41 and repeat the process: 411 / 51

On to step 6:
51 goes into 411 8 times with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 16668.0
If we subtract 408 from 411, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
The number 51 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 16668.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
If we divide 300 by 51, we get 5 and a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 16668.05
Subtracting 255 from 300 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 9:
If we divide 450 by 51, we get 8 and a remainder of 42.
The next digit of our result is 8. 
Result so far: 16668.058
Subtracting 408 from 450 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
51 can be fit into 420 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 16668.0588
The remainder is 12 after subtracting 408 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 16668.0588 with a remainder of 0.00012.
