We're dividing 40173810 by 901 
Our goal is to divide 40173810 by 901.

Advancing to step 1:
901 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 901

On to step 2:
When dividing 40 by 901, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 901

Step 3:
When dividing 401 by 901, we get 0 with a remainder of 401.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 401, we end up with 401.
Include the next digit (7) from the dividend after 401, then repeat: 4017 / 901

Let's proceed to step 4:
When dividing 4017 by 901, we get 4 with a remainder of 413.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 3604 from 4017 leaves us with 413.
Append the next digit (3) from the dividend to 413 and continue with: 4133 / 901

Advancing to step 5:
If we divide 4133 by 901, we get 4 and a remainder of 529.
Use 4 as the next digit of our solution. 
Result so far: 44.0
If we subtract 3604 from 4133, we get 529.
Take the next digit (8) from the dividend and append it to 529, then repeat: 5298 / 901

Going ahead to step 6:
901 goes into 5298 5 times with a remainder of 793.
Use 5 as the next digit of our solution. 
Result so far: 445.0
If we take 4505 away from 5298, we end up with 793.
Fetch the next digit (1) from the dividend, attach it to 793 and continue: 7931 / 901

Advancing to step 7:
When dividing 7931 by 901, we get 8 with a remainder of 723.
Record the quotient 8 as the next digit in the result. 
Result so far: 4458.0
The remainder is 723 after subtracting 7208 from 7931.
Grab the next digit (0) from the dividend, add it to 723, then carry on: 7230 / 901

Going ahead to step 8:
If we divide 7230 by 901, we get 8 and a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 44588.0
Deduct 7208 from 7230 and we're left 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 9:
220 divided by 901 is 0 with a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 44588.0
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 10:
The number 901 fits into 2200 2 times, leaving a remainder of 398.
Use 2 as the next digit of our solution. 
Result so far: 44588.02
If we take 1802 away from 2200, we end up with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Step 11:
If we divide 3980 by 901, we get 4 and a remainder of 376.
Put 4 as the next digit of the answer. 
Result so far: 44588.024
Deduct 3604 from 3980 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 12:
901 can be fit into 3760 4 times, resulting in a remainder of 156.
The next digit of our result is 4. 
Result so far: 44588.0244
If we take 3604 away from 3760, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Our division results in 44588.0244 with a remaining 0.00156.
