We're dividing 49619789 by 850 
Our goal is to divide 49619789 by 850.

On to step 1:
850 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 850

Going ahead to step 2:
49 divided by 850 is 0 with a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Include the next digit (6) from the dividend after 49, then repeat: 496 / 850

Going ahead to step 3:
When dividing 496 by 850, we get 0 with a remainder of 496.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 496 to get 496.
Bring next digit (1) of the dividend behind the 496 and repeat the process: 4961 / 850

On to step 4:
If we divide 4961 by 850, we get 5 and a remainder of 711.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 4250 from 4961 to get 711.
Fetch the next digit (9) from the dividend, attach it to 711 and continue: 7119 / 850

On to step 5:
850 goes into 7119 8 times with a remainder of 319.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
The remainder is 319 after subtracting 6800 from 7119.
Take the next digit (7) from the dividend and append it to 319, then repeat: 3197 / 850

Moving on to step 6:
3197 divided by 850 is 3 with a remainder of 647.
The number 3 becomes the next digit in our result. 
Result so far: 583.0
Deduct 2550 from 3197 and we're left with 647.
Bring next digit (8) of the dividend behind the 647 and repeat the process: 6478 / 850

Step 7:
6478 divided by 850 is 7 with a remainder of 528.
Record the quotient 7 as the next digit in the result. 
Result so far: 5837.0
Subtracting 5950 from 6478 leaves us with 528.
Take the next digit (9) from the dividend and append it to 528, then repeat: 5289 / 850

Moving on to step 8:
If we divide 5289 by 850, we get 6 and a remainder of 189.
The number 6 becomes the next digit in our result. 
Result so far: 58376.0
The remainder is 189 after subtracting 5100 from 5289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

On to step 9:
The number 850 fits into 1890 2 times, leaving a remainder of 190.
The next digit of our result is 2. 
Result so far: 58376.2
If we subtract 1700 from 1890, we 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.

Step 10:
The number 850 fits into 1900 2 times, leaving a remainder of 200.
Put 2 as the next digit of the answer. 
Result so far: 58376.22
Deduct 1700 from 1900 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 58376.22, with a leftover of 0.2.
