Let's divide 39811368 by 454
Our goal is to divide 39811368 by 454.

Advancing to step 1:
The number 454 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 454

Moving on to step 2:
If we divide 39 by 454, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 454

Step 3:
When dividing 398 by 454, we get 0 with a remainder of 398.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 398, we end up with 398.
Append the next digit (1) from the dividend to 398 and continue with: 3981 / 454

Going ahead to step 4:
When dividing 3981 by 454, we get 8 with a remainder of 349.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 3632 from 3981 to get 349.
Grab the next digit (1) from the dividend, add it to 349, then carry on: 3491 / 454

Moving on to step 5:
When dividing 3491 by 454, we get 7 with a remainder of 313.
Use 7 as the next digit of our solution. 
Result so far: 87.0
If we subtract 3178 from 3491, we get 313.
Take the next digit (3) from the dividend and append it to 313, then repeat: 3133 / 454

On to step 6:
3133 divided by 454 is 6 with a remainder of 409.
Put 6 as the next digit of the answer. 
Result so far: 876.0
Deduct 2724 from 3133 and we're left with 409.
Include the next digit (6) from the dividend after 409, then repeat: 4096 / 454

Step 7:
The number 454 fits into 4096 9 times, leaving a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 8769.0
If we take 4086 away from 4096, we end up with 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 454

Going ahead to step 8:
454 goes into 108 0 times with a remainder of 108.
The next digit of our result is 0. 
Result so far: 87690.0
Subtracting 0 from 108 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 9:
454 can be fit into 1080 2 times, resulting in a remainder of 172.
Write down 2 as next digit of the result. 
Result so far: 87690.2
The remainder is 172 after subtracting 908 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 10:
When dividing 1720 by 454, we get 3 with a remainder of 358.
The number 3 becomes the next digit in our result. 
Result so far: 87690.23
If we subtract 1362 from 1720, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 11:
The number 454 fits into 3580 7 times, leaving a remainder of 402.
Record the quotient 7 as the next digit in the result. 
Result so far: 87690.237
Subtract 3178 from 3580 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Advancing to step 12:
4020 divided by 454 is 8 with a remainder of 388.
The number 8 becomes the next digit in our result. 
Result so far: 87690.2378
If we take 3632 away from 4020, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 13:
If we divide 3880 by 454, we get 8 and a remainder of 248.
Use 8 as the next digit of our solution. 
Result so far: 87690.23788
The remainder is 248 after subtracting 3632 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

The final outcome is 87690.23788, with a leftover of 0.000248.
