Let's divide 39900328 by 454
We're looking to find how many times 454 goes into 39900328.

On to step 1:
If we divide 3 by 454, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 454

Let's proceed to step 2:
The number 454 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 454

Moving on to step 3:
When dividing 399 by 454, we get 0 with a remainder of 399.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 399 to get 399.
Grab the next digit (0) from the dividend, add it to 399, then carry on: 3990 / 454

Going ahead to step 4:
The number 454 fits into 3990 8 times, leaving a remainder of 358.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 3632 from 3990, we get 358.
Append the next digit (0) from the dividend to 358 and continue with: 3580 / 454

Moving on to step 5:
3580 divided by 454 is 7 with a remainder of 402.
Put 7 as the next digit of the answer. 
Result so far: 87.0
If we subtract 3178 from 3580, we get 402.
Include the next digit (3) from the dividend after 402, then repeat: 4023 / 454

Advancing to step 6:
454 goes into 4023 8 times with a remainder of 391.
Write down 8 as next digit of the result. 
Result so far: 878.0
Subtract 3632 from 4023 to get 391.
Bring next digit (2) of the dividend behind the 391 and repeat the process: 3912 / 454

Let's proceed to step 7:
454 goes into 3912 8 times with a remainder of 280.
Record the quotient 8 as the next digit in the result. 
Result so far: 8788.0
Deduct 3632 from 3912 and we're left with 280.
Take the next digit (8) from the dividend and append it to 280, then repeat: 2808 / 454

Let's proceed to step 8:
454 can be fit into 2808 6 times, resulting in a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 87886.0
Subtract 2724 from 2808 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 9:
454 can be fit into 840 1 times, resulting in a remainder of 386.
Write down 1 as next digit of the result. 
Result so far: 87886.1
Subtracting 454 from 840 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Moving on to step 10:
3860 divided by 454 is 8 with a remainder of 228.
The number 8 becomes the next digit in our result. 
Result so far: 87886.18
If we subtract 3632 from 3860, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 11:
When dividing 2280 by 454, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 87886.185
Subtracting 2270 from 2280 leaves us 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.

Going ahead to step 12:
The number 454 fits into 100 0 times, leaving a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 87886.185
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 13:
The number 454 fits into 1000 2 times, leaving a remainder of 92.
The number 2 becomes the next digit in our result. 
Result so far: 87886.18502
Deduct 908 from 1000 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 14:
When dividing 920 by 454, we get 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 87886.185022
Deduct 908 from 920 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 87886.185022 with a remaining 1.2e-06.
