We're dividing 851298 by 48 
Our goal is to divide 851298 by 48.

Moving on to step 1:
48 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 48

Advancing to step 2:
When dividing 85 by 48, we get 1 with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 48 from 85, we get 37.
Bring next digit (1) of the dividend behind the 37 and repeat the process: 371 / 48

Step 3:
When dividing 371 by 48, we get 7 with a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 336 from 371 and we're left with 35.
Include the next digit (2) from the dividend after 35, then repeat: 352 / 48

On to step 4:
The number 48 fits into 352 7 times, leaving a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 177.0
Subtract 336 from 352 to get 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 48

Moving on to step 5:
48 goes into 169 3 times with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 1773.0
Subtracting 144 from 169 leaves us with 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 48

Let's proceed to step 6:
258 divided by 48 is 5 with a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 17735.0
Subtracting 240 from 258 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
The number 48 fits into 180 3 times, leaving a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 17735.3
If we take 144 away from 180, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
48 goes into 360 7 times with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 17735.37
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
240 divided by 48 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 17735.375
If we take 240 away from 240, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
If we divide 0 by 48, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17735.375
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
The number 48 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17735.375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 17735.375, with a leftover of 0.0.
