We're dividing 3918099 by 901 
We want to divide 3918099 by 901.

Advancing to step 1:
901 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 901

Moving on to step 2:
901 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 901

Moving on to step 3:
901 can be fit into 391 0 times, resulting in a remainder of 391.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 391 after subtracting 0 from 391.
Take the next digit (8) from the dividend and append it to 391, then repeat: 3918 / 901

Step 4:
3918 divided by 901 is 4 with a remainder of 314.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 3604 from 3918, we get 314.
Take the next digit (0) from the dividend and append it to 314, then repeat: 3140 / 901

On to step 5:
901 can be fit into 3140 3 times, resulting in a remainder of 437.
The next digit of our result is 3. 
Result so far: 43.0
Deduct 2703 from 3140 and we're left with 437.
Fetch the next digit (9) from the dividend, attach it to 437 and continue: 4379 / 901

Step 6:
4379 divided by 901 is 4 with a remainder of 775.
The next digit of our result is 4. 
Result so far: 434.0
The remainder is 775 after subtracting 3604 from 4379.
Bring next digit (9) of the dividend behind the 775 and repeat the process: 7759 / 901

Moving on to step 7:
If we divide 7759 by 901, we get 8 and a remainder of 551.
Write down 8 as next digit of the result. 
Result so far: 4348.0
The remainder is 551 after subtracting 7208 from 7759.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

On to step 8:
When dividing 5510 by 901, we get 6 with a remainder of 104.
The next digit of our result is 6. 
Result so far: 4348.6
Subtract 5406 from 5510 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 9:
1040 divided by 901 is 1 with a remainder of 139.
Record the quotient 1 as the next digit in the result. 
Result so far: 4348.61
If we subtract 901 from 1040, we get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Let's proceed to step 10:
901 can be fit into 1390 1 times, resulting in a remainder of 489.
The next digit of our result is 1. 
Result so far: 4348.611
If we subtract 901 from 1390, we get 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

After the division, we end up with 4348.611 and a remainder of 0.0489.
