We look at the division of 402103 by 48 
We're looking to find how many times 48 goes into 402103.

Moving on to step 1:
4 divided by 48 is 0 with 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 (0) from the dividend and append it to 4, then repeat: 40 / 48

Advancing to step 2:
When dividing 40 by 48, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 48

Advancing to step 3:
If we divide 402 by 48, we get 8 and a remainder of 18.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 384 from 402 to get 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 48

On to step 4:
48 goes into 181 3 times with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Deduct 144 from 181 and we're left with 37.
Fetch the next digit (0) from the dividend, attach it to 37 and continue: 370 / 48

Step 5:
If we divide 370 by 48, we get 7 and a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 837.0
If we subtract 336 from 370, we get 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 48

Going ahead to step 6:
If we divide 343 by 48, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 8377.0
The remainder is 7 after subtracting 336 from 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
48 goes into 70 1 times with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 8377.1
Subtracting 48 from 70 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
48 goes into 220 4 times with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 8377.14
Subtracting 192 from 220 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
When dividing 280 by 48, we get 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 8377.145
Subtract 240 from 280 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
The number 48 fits into 400 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 8377.1458
Subtracting 384 from 400 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
When dividing 160 by 48, we get 3 with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 8377.14583
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
48 goes into 160 3 times with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 8377.145833
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 8377.145833, and the remainder is 1.6e-06.
