We're dividing 71809755 by 451 
We're looking to find how many times 451 goes into 71809755.

On to step 1:
451 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 451

Step 2:
71 divided by 451 is 0 with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Append the next digit (8) from the dividend to 71 and continue with: 718 / 451

Moving on to step 3:
451 goes into 718 1 times with a remainder of 267.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 267 after subtracting 451 from 718.
Grab the next digit (0) from the dividend, add it to 267, then carry on: 2670 / 451

Let's proceed to step 4:
When dividing 2670 by 451, we get 5 with a remainder of 415.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 2255 away from 2670, we end up with 415.
Fetch the next digit (9) from the dividend, attach it to 415 and continue: 4159 / 451

Step 5:
When dividing 4159 by 451, we get 9 with a remainder of 100.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
Deduct 4059 from 4159 and we're left with 100.
Append the next digit (7) from the dividend to 100 and continue with: 1007 / 451

Going ahead to step 6:
1007 divided by 451 is 2 with a remainder of 105.
The number 2 becomes the next digit in our result. 
Result so far: 1592.0
If we take 902 away from 1007, we end up with 105.
Bring next digit (5) of the dividend behind the 105 and repeat the process: 1055 / 451

Let's proceed to step 7:
451 goes into 1055 2 times with a remainder of 153.
The next digit of our result is 2. 
Result so far: 15922.0
Deduct 902 from 1055 and we're left with 153.
Grab the next digit (5) from the dividend, add it to 153, then carry on: 1535 / 451

Step 8:
The number 451 fits into 1535 3 times, leaving a remainder of 182.
Write down 3 as next digit of the result. 
Result so far: 159223.0
Subtract 1353 from 1535 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 9:
451 can be fit into 1820 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 159223.4
If we subtract 1804 from 1820, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
451 goes into 160 0 times with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 159223.4
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 11:
451 can be fit into 1600 3 times, resulting in a remainder of 247.
Use 3 as the next digit of our solution. 
Result so far: 159223.403
Subtracting 1353 from 1600 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Moving on to step 12:
The number 451 fits into 2470 5 times, leaving a remainder of 215.
Use 5 as the next digit of our solution. 
Result so far: 159223.4035
Subtract 2255 from 2470 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 13:
If we divide 2150 by 451, we get 4 and a remainder of 346.
Use 4 as the next digit of our solution. 
Result so far: 159223.40354
If we subtract 1804 from 2150, we get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

On to step 14:
451 can be fit into 3460 7 times, resulting in a remainder of 303.
Record the quotient 7 as the next digit in the result. 
Result so far: 159223.403547
Deduct 3157 from 3460 and we're left with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Going ahead to step 15:
When dividing 3030 by 451, we get 6 with a remainder of 324.
Write down 6 as next digit of the result. 
Result so far: 159223.4035476
If we take 2706 away from 3030, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Moving on to step 16:
451 goes into 3240 7 times with a remainder of 83.
Record the quotient 7 as the next digit in the result. 
Result so far: 159223.40354767
Subtract 3157 from 3240 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

After the division, we end up with 159223.40354767 and a remainder of 8.3e-08.
