Let's divide 68564816 by 451
We want to divide 68564816 by 451.

On to step 1:
451 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 451

Let's proceed to step 2:
451 goes into 68 0 times with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Append the next digit (5) from the dividend to 68 and continue with: 685 / 451

Let's proceed to step 3:
451 goes into 685 1 times with a remainder of 234.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 451 from 685 to get 234.
Fetch the next digit (6) from the dividend, attach it to 234 and continue: 2346 / 451

Moving on to step 4:
451 goes into 2346 5 times with a remainder of 91.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 2255 from 2346 leaves us with 91.
Grab the next digit (4) from the dividend, add it to 91, then carry on: 914 / 451

Step 5:
When dividing 914 by 451, we get 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 152.0
The remainder is 12 after subtracting 902 from 914.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 451

Moving on to step 6:
If we divide 128 by 451, we get 0 and a remainder of 128.
The next digit of our result is 0. 
Result so far: 1520.0
If we subtract 0 from 128, we get 128.
Take the next digit (1) from the dividend and append it to 128, then repeat: 1281 / 451

On to step 7:
When dividing 1281 by 451, we get 2 with a remainder of 379.
Use 2 as the next digit of our solution. 
Result so far: 15202.0
If we take 902 away from 1281, we end up with 379.
Fetch the next digit (6) from the dividend, attach it to 379 and continue: 3796 / 451

Moving on to step 8:
If we divide 3796 by 451, we get 8 and a remainder of 188.
The number 8 becomes the next digit in our result. 
Result so far: 152028.0
If we subtract 3608 from 3796, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 9:
451 goes into 1880 4 times with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 152028.4
Subtracting 1804 from 1880 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 10:
When dividing 760 by 451, we get 1 with a remainder of 309.
The next digit of our result is 1. 
Result so far: 152028.41
The remainder is 309 after subtracting 451 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Advancing to step 11:
451 can be fit into 3090 6 times, resulting in a remainder of 384.
Write down 6 as next digit of the result. 
Result so far: 152028.416
The remainder is 384 after subtracting 2706 from 3090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 12:
3840 divided by 451 is 8 with a remainder of 232.
The number 8 becomes the next digit in our result. 
Result so far: 152028.4168
If we take 3608 away from 3840, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 13:
The number 451 fits into 2320 5 times, leaving a remainder of 65.
The next digit of our result is 5. 
Result so far: 152028.41685
If we subtract 2255 from 2320, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 14:
650 divided by 451 is 1 with a remainder of 199.
Record the quotient 1 as the next digit in the result. 
Result so far: 152028.416851
If we subtract 451 from 650, we get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

On to step 15:
If we divide 1990 by 451, we get 4 and a remainder of 186.
The next digit of our result is 4. 
Result so far: 152028.4168514
Subtracting 1804 from 1990 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 16:
If we divide 1860 by 451, we get 4 and a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 152028.41685144
The remainder is 56 after subtracting 1804 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 152028.41685144 and a remainder of 5.6e-08.
