68433006 ÷ 451 
Our goal is to divide 68433006 by 451.

Going ahead to step 1:
451 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 451

Going ahead to step 2:
The number 451 fits into 68 0 times, leaving a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Include the next digit (4) from the dividend after 68, then repeat: 684 / 451

On to step 3:
451 goes into 684 1 times with a remainder of 233.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 451 away from 684, we end up with 233.
Fetch the next digit (3) from the dividend, attach it to 233 and continue: 2333 / 451

Going ahead to step 4:
If we divide 2333 by 451, we get 5 and a remainder of 78.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 2255 away from 2333, we end up with 78.
Append the next digit (3) from the dividend to 78 and continue with: 783 / 451

Let's proceed to step 5:
If we divide 783 by 451, we get 1 and a remainder of 332.
Use 1 as the next digit of our solution. 
Result so far: 151.0
Deduct 451 from 783 and we're left with 332.
Include the next digit (0) from the dividend after 332, then repeat: 3320 / 451

Moving on to step 6:
451 can be fit into 3320 7 times, resulting in a remainder of 163.
The number 7 becomes the next digit in our result. 
Result so far: 1517.0
If we take 3157 away from 3320, we end up with 163.
Bring next digit (0) of the dividend behind the 163 and repeat the process: 1630 / 451

Moving on to step 7:
When dividing 1630 by 451, we get 3 with a remainder of 277.
Write down 3 as next digit of the result. 
Result so far: 15173.0
Subtract 1353 from 1630 to get 277.
Include the next digit (6) from the dividend after 277, then repeat: 2776 / 451

Going ahead to step 8:
451 goes into 2776 6 times with a remainder of 70.
Use 6 as the next digit of our solution. 
Result so far: 151736.0
If we take 2706 away from 2776, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
When dividing 700 by 451, we get 1 with a remainder of 249.
Write down 1 as next digit of the result. 
Result so far: 151736.1
The remainder is 249 after subtracting 451 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Advancing to step 10:
When dividing 2490 by 451, we get 5 with a remainder of 235.
Record the quotient 5 as the next digit in the result. 
Result so far: 151736.15
If we take 2255 away from 2490, we end up with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 11:
451 goes into 2350 5 times with a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 151736.155
The remainder is 95 after subtracting 2255 from 2350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

After the division, we end up with 151736.155 and a remainder of 0.0095.
