We divide 8015117 by 428
Our goal is to divide 8015117 by 428.

Step 1:
The number 428 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 428

Moving on to step 2:
The number 428 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Fetch the next digit (1) from the dividend, attach it to 80 and continue: 801 / 428

Going ahead to step 3:
When dividing 801 by 428, we get 1 with a remainder of 373.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 428 from 801 and we're left with 373.
Bring next digit (5) of the dividend behind the 373 and repeat the process: 3735 / 428

Step 4:
428 can be fit into 3735 8 times, resulting in a remainder of 311.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 311 after subtracting 3424 from 3735.
Include the next digit (1) from the dividend after 311, then repeat: 3111 / 428

Moving on to step 5:
428 goes into 3111 7 times with a remainder of 115.
Put 7 as the next digit of the answer. 
Result so far: 187.0
Subtract 2996 from 3111 to get 115.
Include the next digit (1) from the dividend after 115, then repeat: 1151 / 428

Moving on to step 6:
The number 428 fits into 1151 2 times, leaving a remainder of 295.
Use 2 as the next digit of our solution. 
Result so far: 1872.0
If we subtract 856 from 1151, we get 295.
Include the next digit (7) from the dividend after 295, then repeat: 2957 / 428

Moving on to step 7:
428 can be fit into 2957 6 times, resulting in a remainder of 389.
Put 6 as the next digit of the answer. 
Result so far: 18726.0
If we subtract 2568 from 2957, we get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

On to step 8:
428 goes into 3890 9 times with a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 18726.9
If we subtract 3852 from 3890, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
428 goes into 380 0 times with a remainder of 380.
Use 0 as the next digit of our solution. 
Result so far: 18726.9
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 10:
When dividing 3800 by 428, we get 8 with a remainder of 376.
Record the quotient 8 as the next digit in the result. 
Result so far: 18726.908
If we subtract 3424 from 3800, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 11:
If we divide 3760 by 428, we get 8 and a remainder of 336.
Write down 8 as next digit of the result. 
Result so far: 18726.9088
Deduct 3424 from 3760 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The final outcome is 18726.9088, with a leftover of 0.00336.
