Let's divide 42837837 by 851
We want to figure out the number of times 42837837 can be divided by 851.

On to step 1:
4 divided by 851 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 851

Step 2:
42 divided by 851 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 851

Advancing to step 3:
When dividing 428 by 851, we get 0 with a remainder of 428.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 428, we get 428.
Take the next digit (3) from the dividend and append it to 428, then repeat: 4283 / 851

Advancing to step 4:
If we divide 4283 by 851, we get 5 and a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 4255 from 4283, we get 28.
Take the next digit (7) from the dividend and append it to 28, then repeat: 287 / 851

On to step 5:
287 divided by 851 is 0 with a remainder of 287.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtracting 0 from 287 leaves us with 287.
Bring next digit (8) of the dividend behind the 287 and repeat the process: 2878 / 851

On to step 6:
2878 divided by 851 is 3 with a remainder of 325.
The number 3 becomes the next digit in our result. 
Result so far: 503.0
Subtracting 2553 from 2878 leaves us with 325.
Append the next digit (3) from the dividend to 325 and continue with: 3253 / 851

Advancing to step 7:
If we divide 3253 by 851, we get 3 and a remainder of 700.
Put 3 as the next digit of the answer. 
Result so far: 5033.0
Deduct 2553 from 3253 and we're left with 700.
Bring next digit (7) of the dividend behind the 700 and repeat the process: 7007 / 851

Let's proceed to step 8:
When dividing 7007 by 851, we get 8 with a remainder of 199.
The number 8 becomes the next digit in our result. 
Result so far: 50338.0
The remainder is 199 after subtracting 6808 from 7007.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Going ahead to step 9:
851 can be fit into 1990 2 times, resulting in a remainder of 288.
The number 2 becomes the next digit in our result. 
Result so far: 50338.2
Subtract 1702 from 1990 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 10:
When dividing 2880 by 851, we get 3 with a remainder of 327.
Use 3 as the next digit of our solution. 
Result so far: 50338.23
Subtracting 2553 from 2880 leaves us with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Moving on to step 11:
When dividing 3270 by 851, we get 3 with a remainder of 717.
Write down 3 as next digit of the result. 
Result so far: 50338.233
Subtracting 2553 from 3270 leaves us with 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

The quotient of the division is 50338.233, and the remainder is 0.0717.
