48487430 divided by 851 
We want to divide 48487430 by 851.

Moving on to step 1:
The number 851 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 851

Moving on to step 2:
851 goes into 48 0 times with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Bring next digit (4) of the dividend behind the 48 and repeat the process: 484 / 851

Going ahead to step 3:
484 divided by 851 is 0 with a remainder of 484.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 484 to get 484.
Append the next digit (8) from the dividend to 484 and continue with: 4848 / 851

Going ahead to step 4:
If we divide 4848 by 851, we get 5 and a remainder of 593.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 4255 from 4848 and we're left with 593.
Append the next digit (7) from the dividend to 593 and continue with: 5937 / 851

Moving on to step 5:
851 goes into 5937 6 times with a remainder of 831.
The next digit of our result is 6. 
Result so far: 56.0
If we subtract 5106 from 5937, we get 831.
Grab the next digit (4) from the dividend, add it to 831, then carry on: 8314 / 851

Moving on to step 6:
If we divide 8314 by 851, we get 9 and a remainder of 655.
Write down 9 as next digit of the result. 
Result so far: 569.0
Subtracting 7659 from 8314 leaves us with 655.
Append the next digit (3) from the dividend to 655 and continue with: 6553 / 851

Let's proceed to step 7:
If we divide 6553 by 851, we get 7 and a remainder of 596.
The next digit of our result is 7. 
Result so far: 5697.0
If we take 5957 away from 6553, we end up with 596.
Bring next digit (0) of the dividend behind the 596 and repeat the process: 5960 / 851

Let's proceed to step 8:
The number 851 fits into 5960 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 56977.0
Subtract 5957 from 5960 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
If we divide 30 by 851, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 56977.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
851 goes into 300 0 times with a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 56977.0
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 56977.0, with a leftover of 0.3.
