We're dividing 42025518 by 850 
Let's see how many times 850 fits into 42025518.

Let's proceed to step 1:
850 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 850

Advancing to step 2:
850 goes into 42 0 times with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 850

Going ahead to step 3:
850 can be fit into 420 0 times, resulting in a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 420, we get 420.
Append the next digit (2) from the dividend to 420 and continue with: 4202 / 850

Advancing to step 4:
4202 divided by 850 is 4 with a remainder of 802.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 802 after subtracting 3400 from 4202.
Include the next digit (5) from the dividend after 802, then repeat: 8025 / 850

Moving on to step 5:
8025 divided by 850 is 9 with a remainder of 375.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtract 7650 from 8025 to get 375.
Append the next digit (5) from the dividend to 375 and continue with: 3755 / 850

Let's proceed to step 6:
When dividing 3755 by 850, we get 4 with a remainder of 355.
Put 4 as the next digit of the answer. 
Result so far: 494.0
Deduct 3400 from 3755 and we're left with 355.
Take the next digit (1) from the dividend and append it to 355, then repeat: 3551 / 850

Going ahead to step 7:
The number 850 fits into 3551 4 times, leaving a remainder of 151.
Record the quotient 4 as the next digit in the result. 
Result so far: 4944.0
If we subtract 3400 from 3551, we get 151.
Grab the next digit (8) from the dividend, add it to 151, then carry on: 1518 / 850

Let's proceed to step 8:
850 goes into 1518 1 times with a remainder of 668.
The next digit of our result is 1. 
Result so far: 49441.0
If we subtract 850 from 1518, we get 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Going ahead to step 9:
The number 850 fits into 6680 7 times, leaving a remainder of 730.
The number 7 becomes the next digit in our result. 
Result so far: 49441.7
Subtracting 5950 from 6680 leaves us with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Moving on to step 10:
When dividing 7300 by 850, we get 8 with a remainder of 500.
Put 8 as the next digit of the answer. 
Result so far: 49441.78
The remainder is 500 after subtracting 6800 from 7300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 11:
850 can be fit into 5000 5 times, resulting in a remainder of 750.
The number 5 becomes the next digit in our result. 
Result so far: 49441.785
If we subtract 4250 from 5000, we get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Going ahead to step 12:
850 goes into 7500 8 times with a remainder of 700.
The next digit of our result is 8. 
Result so far: 49441.7858
If we subtract 6800 from 7500, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 13:
The number 850 fits into 7000 8 times, leaving a remainder of 200.
The number 8 becomes the next digit in our result. 
Result so far: 49441.78588
If we take 6800 away from 7000, we end up 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.

After the division, we end up with 49441.78588 and a remainder of 0.0002.
