We're dividing 42863199 by 851 
We want to figure out the number of times 42863199 can be divided by 851.

Going ahead 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
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 851

On to step 2:
If we divide 42 by 851, we get 0 and a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 851

Going ahead to step 3:
851 goes into 428 0 times 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.
Append the next digit (6) from the dividend to 428 and continue with: 4286 / 851

Going ahead to step 4:
When dividing 4286 by 851, we get 5 with a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 4255 away from 4286, we end up with 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 851

Advancing to step 5:
313 divided by 851 is 0 with a remainder of 313.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
If we subtract 0 from 313, we get 313.
Bring next digit (1) of the dividend behind the 313 and repeat the process: 3131 / 851

Going ahead to step 6:
851 goes into 3131 3 times with a remainder of 578.
The next digit of our result is 3. 
Result so far: 503.0
If we take 2553 away from 3131, we end up with 578.
Bring next digit (9) of the dividend behind the 578 and repeat the process: 5789 / 851

Moving on to step 7:
If we divide 5789 by 851, we get 6 and a remainder of 683.
Record the quotient 6 as the next digit in the result. 
Result so far: 5036.0
Subtract 5106 from 5789 to get 683.
Fetch the next digit (9) from the dividend, attach it to 683 and continue: 6839 / 851

On to step 8:
The number 851 fits into 6839 8 times, leaving a remainder of 31.
Put 8 as the next digit of the answer. 
Result so far: 50368.0
If we take 6808 away from 6839, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 9:
When dividing 310 by 851, we get 0 with a remainder of 310.
Write down 0 as next digit of the result. 
Result so far: 50368.0
Deduct 0 from 310 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 10:
3100 divided by 851 is 3 with a remainder of 547.
The number 3 becomes the next digit in our result. 
Result so far: 50368.03
If we subtract 2553 from 3100, we get 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Moving on to step 11:
The number 851 fits into 5470 6 times, leaving a remainder of 364.
Record the quotient 6 as the next digit in the result. 
Result so far: 50368.036
If we subtract 5106 from 5470, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 12:
If we divide 3640 by 851, we get 4 and a remainder of 236.
Write down 4 as next digit of the result. 
Result so far: 50368.0364
Subtracting 3404 from 3640 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 13:
851 goes into 2360 2 times with a remainder of 658.
Use 2 as the next digit of our solution. 
Result so far: 50368.03642
Deduct 1702 from 2360 and we're left with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Moving on to step 14:
If we divide 6580 by 851, we get 7 and a remainder of 623.
Write down 7 as next digit of the result. 
Result so far: 50368.036427
Deduct 5957 from 6580 and we're left with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Step 15:
851 goes into 6230 7 times with a remainder of 273.
Use 7 as the next digit of our solution. 
Result so far: 50368.0364277
Deduct 5957 from 6230 and we're left with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

After the division, we end up with 50368.0364277 and a remainder of 2.73e-06.
