We're dividing 18375384 by 401 
Let's see how many times 401 fits into 18375384.

Step 1:
If we divide 1 by 401, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 401

Step 2:
401 goes into 18 0 times with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 401

Going ahead to step 3:
When dividing 183 by 401, we get 0 with a remainder of 183.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 183 to get 183.
Include the next digit (7) from the dividend after 183, then repeat: 1837 / 401

Moving on to step 4:
If we divide 1837 by 401, we get 4 and a remainder of 233.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 1604 from 1837, we get 233.
Take the next digit (5) from the dividend and append it to 233, then repeat: 2335 / 401

Advancing to step 5:
If we divide 2335 by 401, we get 5 and a remainder of 330.
The next digit of our result is 5. 
Result so far: 45.0
If we subtract 2005 from 2335, we get 330.
Bring next digit (3) of the dividend behind the 330 and repeat the process: 3303 / 401

On to step 6:
3303 divided by 401 is 8 with a remainder of 95.
Use 8 as the next digit of our solution. 
Result so far: 458.0
If we take 3208 away from 3303, we end up with 95.
Fetch the next digit (8) from the dividend, attach it to 95 and continue: 958 / 401

On to step 7:
When dividing 958 by 401, we get 2 with a remainder of 156.
Write down 2 as next digit of the result. 
Result so far: 4582.0
Subtracting 802 from 958 leaves us with 156.
Append the next digit (4) from the dividend to 156 and continue with: 1564 / 401

On to step 8:
401 goes into 1564 3 times with a remainder of 361.
Use 3 as the next digit of our solution. 
Result so far: 45823.0
Subtract 1203 from 1564 to get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Going ahead to step 9:
When dividing 3610 by 401, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 45823.9
Subtracting 3609 from 3610 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
If we divide 10 by 401, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 45823.9
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
When dividing 100 by 401, we get 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 45823.9
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 45823.9, with a leftover of 0.01.
