We look at the division of 42674664 by 851 
We're looking to find how many times 851 goes into 42674664.

Going ahead to step 1:
851 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 851

Advancing to step 2:
851 can be fit into 42 0 times, resulting in 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.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 851

Let's proceed to step 3:
If we divide 426 by 851, we get 0 and a remainder of 426.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 426 to get 426.
Fetch the next digit (7) from the dividend, attach it to 426 and continue: 4267 / 851

Going ahead to step 4:
The number 851 fits into 4267 5 times, leaving a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 4255 from 4267, we get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 851

Going ahead to step 5:
If we divide 124 by 851, we get 0 and a remainder of 124.
Put 0 as the next digit of the answer. 
Result so far: 50.0
If we subtract 0 from 124, we get 124.
Append the next digit (6) from the dividend to 124 and continue with: 1246 / 851

Let's proceed to step 6:
1246 divided by 851 is 1 with a remainder of 395.
Put 1 as the next digit of the answer. 
Result so far: 501.0
Subtract 851 from 1246 to get 395.
Include the next digit (6) from the dividend after 395, then repeat: 3956 / 851

Moving on to step 7:
If we divide 3956 by 851, we get 4 and a remainder of 552.
Put 4 as the next digit of the answer. 
Result so far: 5014.0
The remainder is 552 after subtracting 3404 from 3956.
Grab the next digit (4) from the dividend, add it to 552, then carry on: 5524 / 851

Moving on to step 8:
If we divide 5524 by 851, we get 6 and a remainder of 418.
Put 6 as the next digit of the answer. 
Result so far: 50146.0
Subtracting 5106 from 5524 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Moving on to step 9:
If we divide 4180 by 851, we get 4 and a remainder of 776.
Put 4 as the next digit of the answer. 
Result so far: 50146.4
Deduct 3404 from 4180 and we're left with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Moving on to step 10:
851 goes into 7760 9 times with a remainder of 101.
The next digit of our result is 9. 
Result so far: 50146.49
The remainder is 101 after subtracting 7659 from 7760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 11:
851 can be fit into 1010 1 times, resulting in a remainder of 159.
The next digit of our result is 1. 
Result so far: 50146.491
If we take 851 away from 1010, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Moving on to step 12:
The number 851 fits into 1590 1 times, leaving a remainder of 739.
The next digit of our result is 1. 
Result so far: 50146.4911
If we subtract 851 from 1590, we get 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

The final outcome is 50146.4911, with a leftover of 0.00739.
