We're dividing 42140658 by 851 
Let's see how many times 851 fits into 42140658.

On to step 1:
851 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 851

Moving on to step 2:
42 divided by 851 is 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 851

Let's proceed to step 3:
851 can be fit into 421 0 times, resulting in a remainder of 421.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 421 to get 421.
Include the next digit (4) from the dividend after 421, then repeat: 4214 / 851

Step 4:
4214 divided by 851 is 4 with a remainder of 810.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 3404 away from 4214, we end up with 810.
Include the next digit (0) from the dividend after 810, then repeat: 8100 / 851

Advancing to step 5:
851 goes into 8100 9 times with a remainder of 441.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
If we take 7659 away from 8100, we end up with 441.
Bring next digit (6) of the dividend behind the 441 and repeat the process: 4416 / 851

On to step 6:
851 goes into 4416 5 times with a remainder of 161.
Put 5 as the next digit of the answer. 
Result so far: 495.0
Subtract 4255 from 4416 to get 161.
Fetch the next digit (5) from the dividend, attach it to 161 and continue: 1615 / 851

Advancing to step 7:
1615 divided by 851 is 1 with a remainder of 764.
Put 1 as the next digit of the answer. 
Result so far: 4951.0
Subtract 851 from 1615 to get 764.
Include the next digit (8) from the dividend after 764, then repeat: 7648 / 851

On to step 8:
7648 divided by 851 is 8 with a remainder of 840.
The number 8 becomes the next digit in our result. 
Result so far: 49518.0
Deduct 6808 from 7648 and we're left with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Moving on to step 9:
If we divide 8400 by 851, we get 9 and a remainder of 741.
The next digit of our result is 9. 
Result so far: 49518.9
If we take 7659 away from 8400, we end up with 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7410, and continue the process.

Moving on to step 10:
851 can be fit into 7410 8 times, resulting in a remainder of 602.
Record the quotient 8 as the next digit in the result. 
Result so far: 49518.98
Subtract 6808 from 7410 to get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Moving on to step 11:
If we divide 6020 by 851, we get 7 and a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 49518.987
Subtract 5957 from 6020 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 12:
The number 851 fits into 630 0 times, leaving a remainder of 630.
Use 0 as the next digit of our solution. 
Result so far: 49518.987
Subtracting 0 from 630 leaves us with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 13:
The number 851 fits into 6300 7 times, leaving a remainder of 343.
Record the quotient 7 as the next digit in the result. 
Result so far: 49518.98707
If we take 5957 away from 6300, we end up with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Let's proceed to step 14:
851 goes into 3430 4 times with a remainder of 26.
The next digit of our result is 4. 
Result so far: 49518.987074
If we take 3404 away from 3430, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 15:
If we divide 260 by 851, we get 0 and a remainder of 260.
Record the quotient 0 as the next digit in the result. 
Result so far: 49518.987074
The remainder is 260 after subtracting 0 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 16:
When dividing 2600 by 851, we get 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 49518.98707403
Subtract 2553 from 2600 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The quotient of the division is 49518.98707403, and the remainder is 4.7e-08.
