Let's divide 12480286 by 901
Let's see how many times 901 fits into 12480286.

On to step 1:
When dividing 1 by 901, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 901

Advancing to step 2:
901 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 901

Advancing to step 3:
901 can be fit into 124 0 times, resulting in a remainder of 124.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 124 to get 124.
Bring next digit (8) of the dividend behind the 124 and repeat the process: 1248 / 901

Moving on to step 4:
When dividing 1248 by 901, we get 1 with a remainder of 347.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 901 from 1248, we get 347.
Grab the next digit (0) from the dividend, add it to 347, then carry on: 3470 / 901

On to step 5:
3470 divided by 901 is 3 with a remainder of 767.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 2703 away from 3470, we end up with 767.
Fetch the next digit (2) from the dividend, attach it to 767 and continue: 7672 / 901

Step 6:
When dividing 7672 by 901, we get 8 with a remainder of 464.
Use 8 as the next digit of our solution. 
Result so far: 138.0
Subtract 7208 from 7672 to get 464.
Append the next digit (8) from the dividend to 464 and continue with: 4648 / 901

Let's proceed to step 7:
If we divide 4648 by 901, we get 5 and a remainder of 143.
Write down 5 as next digit of the result. 
Result so far: 1385.0
Deduct 4505 from 4648 and we're left with 143.
Fetch the next digit (6) from the dividend, attach it to 143 and continue: 1436 / 901

Moving on to step 8:
1436 divided by 901 is 1 with a remainder of 535.
The number 1 becomes the next digit in our result. 
Result so far: 13851.0
The remainder is 535 after subtracting 901 from 1436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Moving on to step 9:
If we divide 5350 by 901, we get 5 and a remainder of 845.
Write down 5 as next digit of the result. 
Result so far: 13851.5
Subtract 4505 from 5350 to get 845.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8450, and continue the process.

Let's proceed to step 10:
If we divide 8450 by 901, we get 9 and a remainder of 341.
Put 9 as the next digit of the answer. 
Result so far: 13851.59
If we take 8109 away from 8450, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Step 11:
3410 divided by 901 is 3 with a remainder of 707.
Use 3 as the next digit of our solution. 
Result so far: 13851.593
If we subtract 2703 from 3410, we get 707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7070, and continue the process.

Step 12:
If we divide 7070 by 901, we get 7 and a remainder of 763.
Put 7 as the next digit of the answer. 
Result so far: 13851.5937
Subtract 6307 from 7070 to get 763.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7630, and continue the process.

Moving on to step 13:
7630 divided by 901 is 8 with a remainder of 422.
Put 8 as the next digit of the answer. 
Result so far: 13851.59378
Subtract 7208 from 7630 to get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Moving on to step 14:
The number 901 fits into 4220 4 times, leaving a remainder of 616.
Use 4 as the next digit of our solution. 
Result so far: 13851.593784
Subtracting 3604 from 4220 leaves us with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Let's proceed to step 15:
The number 901 fits into 6160 6 times, leaving a remainder of 754.
Write down 6 as next digit of the result. 
Result so far: 13851.5937846
Subtract 5406 from 6160 to get 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Let's proceed to step 16:
901 can be fit into 7540 8 times, resulting in a remainder of 332.
The next digit of our result is 8. 
Result so far: 13851.59378468
The remainder is 332 after subtracting 7208 from 7540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

After the division, we end up with 13851.59378468 and a remainder of 3.32e-07.
