71434007 ÷ 451 
We want to divide 71434007 by 451.

On to step 1:
When dividing 7 by 451, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 451

Advancing to step 2:
The number 451 fits into 71 0 times, leaving a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Grab the next digit (4) from the dividend, add it to 71, then carry on: 714 / 451

Step 3:
The number 451 fits into 714 1 times, leaving a remainder of 263.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 263 after subtracting 451 from 714.
Bring next digit (3) of the dividend behind the 263 and repeat the process: 2633 / 451

Advancing to step 4:
2633 divided by 451 is 5 with a remainder of 378.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 2255 from 2633, we get 378.
Include the next digit (4) from the dividend after 378, then repeat: 3784 / 451

Step 5:
The number 451 fits into 3784 8 times, leaving a remainder of 176.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
If we subtract 3608 from 3784, we get 176.
Include the next digit (0) from the dividend after 176, then repeat: 1760 / 451

Moving on to step 6:
451 can be fit into 1760 3 times, resulting in a remainder of 407.
The number 3 becomes the next digit in our result. 
Result so far: 1583.0
Deduct 1353 from 1760 and we're left with 407.
Bring next digit (0) of the dividend behind the 407 and repeat the process: 4070 / 451

Moving on to step 7:
451 goes into 4070 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 15839.0
If we subtract 4059 from 4070, we get 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 451

Let's proceed to step 8:
When dividing 117 by 451, we get 0 with a remainder of 117.
Put 0 as the next digit of the answer. 
Result so far: 158390.0
Subtract 0 from 117 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 9:
451 goes into 1170 2 times with a remainder of 268.
Use 2 as the next digit of our solution. 
Result so far: 158390.2
Deduct 902 from 1170 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Let's proceed to step 10:
If we divide 2680 by 451, we get 5 and a remainder of 425.
Write down 5 as next digit of the result. 
Result so far: 158390.25
Deduct 2255 from 2680 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Going ahead to step 11:
If we divide 4250 by 451, we get 9 and a remainder of 191.
Put 9 as the next digit of the answer. 
Result so far: 158390.259
The remainder is 191 after subtracting 4059 from 4250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Moving on to step 12:
451 goes into 1910 4 times with a remainder of 106.
The next digit of our result is 4. 
Result so far: 158390.2594
If we take 1804 away from 1910, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 13:
When dividing 1060 by 451, we get 2 with a remainder of 158.
Write down 2 as next digit of the result. 
Result so far: 158390.25942
Deduct 902 from 1060 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 14:
451 can be fit into 1580 3 times, resulting in a remainder of 227.
Use 3 as the next digit of our solution. 
Result so far: 158390.259423
Deduct 1353 from 1580 and we're left with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Advancing to step 15:
The number 451 fits into 2270 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 158390.2594235
If we take 2255 away from 2270, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 16:
If we divide 150 by 451, we get 0 and a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 158390.2594235
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Our division results in 158390.2594235 with a remaining 1.5e-07.
