We look at the division of 48518961 by 902 
Let's see how many times 902 fits into 48518961.

Advancing to step 1:
The number 902 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 902

Going ahead to step 2:
When dividing 48 by 902, we get 0 with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Take the next digit (5) from the dividend and append it to 48, then repeat: 485 / 902

Step 3:
902 goes into 485 0 times with a remainder of 485.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 485 and we're left with 485.
Take the next digit (1) from the dividend and append it to 485, then repeat: 4851 / 902

Moving on to step 4:
4851 divided by 902 is 5 with a remainder of 341.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 4510 from 4851 and we're left with 341.
Grab the next digit (8) from the dividend, add it to 341, then carry on: 3418 / 902

Going ahead to step 5:
3418 divided by 902 is 3 with a remainder of 712.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
The remainder is 712 after subtracting 2706 from 3418.
Include the next digit (9) from the dividend after 712, then repeat: 7129 / 902

Step 6:
The number 902 fits into 7129 7 times, leaving a remainder of 815.
Record the quotient 7 as the next digit in the result. 
Result so far: 537.0
Deduct 6314 from 7129 and we're left with 815.
Fetch the next digit (6) from the dividend, attach it to 815 and continue: 8156 / 902

Step 7:
902 can be fit into 8156 9 times, resulting in a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 5379.0
If we subtract 8118 from 8156, we get 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 902

Let's proceed to step 8:
The number 902 fits into 381 0 times, leaving a remainder of 381.
The number 0 becomes the next digit in our result. 
Result so far: 53790.0
If we subtract 0 from 381, we get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Let's proceed to step 9:
902 can be fit into 3810 4 times, resulting in a remainder of 202.
Record the quotient 4 as the next digit in the result. 
Result so far: 53790.4
Subtract 3608 from 3810 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 10:
902 goes into 2020 2 times with a remainder of 216.
The next digit of our result is 2. 
Result so far: 53790.42
Deduct 1804 from 2020 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 11:
2160 divided by 902 is 2 with a remainder of 356.
The number 2 becomes the next digit in our result. 
Result so far: 53790.422
If we take 1804 away from 2160, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

After the division, we end up with 53790.422 and a remainder of 0.0356.
