Let's divide 851139 by 50
Let's see how many times 50 fits into 851139.

Step 1:
The number 50 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 50

Advancing to step 2:
When dividing 85 by 50, we get 1 with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 50 from 85 to get 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 50

Going ahead to step 3:
50 goes into 351 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 350 from 351 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 50

Let's proceed to step 4:
If we divide 11 by 50, we get 0 and a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 170.0
The remainder is 11 after subtracting 0 from 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 50

Going ahead to step 5:
If we divide 113 by 50, we get 2 and a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 1702.0
Subtract 100 from 113 to get 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 50

Advancing to step 6:
139 divided by 50 is 2 with a remainder of 39.
Record the quotient 2 as the next digit in the result. 
Result so far: 17022.0
Deduct 100 from 139 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
50 can be fit into 390 7 times, resulting in a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 17022.7
Deduct 350 from 390 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
When dividing 400 by 50, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 17022.78
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
50 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17022.78
The remainder is 0 after subtracting 0 from 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 10:
If we divide 0 by 50, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17022.78
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.

Our division results in 17022.78 with a remaining 0.0.
