We're dividing 42548982 by 902 
Let's see how many times 902 fits into 42548982.

Let's proceed to step 1:
When dividing 4 by 902, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 902

Advancing to step 2:
902 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Grab the next digit (5) from the dividend, add it to 42, then carry on: 425 / 902

Advancing to step 3:
902 goes into 425 0 times with a remainder of 425.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 425 leaves us with 425.
Fetch the next digit (4) from the dividend, attach it to 425 and continue: 4254 / 902

On to step 4:
The number 902 fits into 4254 4 times, leaving a remainder of 646.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 3608 from 4254 and we're left with 646.
Take the next digit (8) from the dividend and append it to 646, then repeat: 6468 / 902

On to step 5:
6468 divided by 902 is 7 with a remainder of 154.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we take 6314 away from 6468, we end up with 154.
Take the next digit (9) from the dividend and append it to 154, then repeat: 1549 / 902

Going ahead to step 6:
The number 902 fits into 1549 1 times, leaving a remainder of 647.
The number 1 becomes the next digit in our result. 
Result so far: 471.0
Subtract 902 from 1549 to get 647.
Bring next digit (8) of the dividend behind the 647 and repeat the process: 6478 / 902

Going ahead to step 7:
When dividing 6478 by 902, we get 7 with a remainder of 164.
Write down 7 as next digit of the result. 
Result so far: 4717.0
Subtracting 6314 from 6478 leaves us with 164.
Include the next digit (2) from the dividend after 164, then repeat: 1642 / 902

Let's proceed to step 8:
When dividing 1642 by 902, we get 1 with a remainder of 740.
Record the quotient 1 as the next digit in the result. 
Result so far: 47171.0
If we subtract 902 from 1642, we get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Advancing to step 9:
The number 902 fits into 7400 8 times, leaving a remainder of 184.
Record the quotient 8 as the next digit in the result. 
Result so far: 47171.8
If we take 7216 away from 7400, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 10:
1840 divided by 902 is 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 47171.82
Subtract 1804 from 1840 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
The number 902 fits into 360 0 times, leaving a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 47171.82
If we subtract 0 from 360, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 12:
3600 divided by 902 is 3 with a remainder of 894.
Record the quotient 3 as the next digit in the result. 
Result so far: 47171.8203
Deduct 2706 from 3600 and we're left with 894.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8940, and continue the process.

Step 13:
8940 divided by 902 is 9 with a remainder of 822.
The next digit of our result is 9. 
Result so far: 47171.82039
Subtracting 8118 from 8940 leaves us with 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

Moving on to step 14:
902 can be fit into 8220 9 times, resulting in a remainder of 102.
Put 9 as the next digit of the answer. 
Result so far: 47171.820399
If we take 8118 away from 8220, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The final result is 47171.820399 with a remainder of 1.02e-05.
