71915431 divided by 456 
We want to figure out the number of times 71915431 can be divided by 456.

Advancing to step 1:
456 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 456

Advancing to step 2:
The number 456 fits into 71 0 times, leaving a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Fetch the next digit (9) from the dividend, attach it to 71 and continue: 719 / 456

Step 3:
When dividing 719 by 456, we get 1 with a remainder of 263.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 456 from 719 leaves us with 263.
Fetch the next digit (1) from the dividend, attach it to 263 and continue: 2631 / 456

On to step 4:
2631 divided by 456 is 5 with a remainder of 351.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 2280 away from 2631, we end up with 351.
Take the next digit (5) from the dividend and append it to 351, then repeat: 3515 / 456

Going ahead to step 5:
If we divide 3515 by 456, we get 7 and a remainder of 323.
Put 7 as the next digit of the answer. 
Result so far: 157.0
Deduct 3192 from 3515 and we're left with 323.
Bring next digit (4) of the dividend behind the 323 and repeat the process: 3234 / 456

Step 6:
The number 456 fits into 3234 7 times, leaving a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 1577.0
Subtract 3192 from 3234 to get 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 456

Step 7:
The number 456 fits into 423 0 times, leaving a remainder of 423.
Use 0 as the next digit of our solution. 
Result so far: 15770.0
If we subtract 0 from 423, we get 423.
Take the next digit (1) from the dividend and append it to 423, then repeat: 4231 / 456

Step 8:
When dividing 4231 by 456, we get 9 with a remainder of 127.
The next digit of our result is 9. 
Result so far: 157709.0
If we subtract 4104 from 4231, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 9:
456 can be fit into 1270 2 times, resulting in a remainder of 358.
Use 2 as the next digit of our solution. 
Result so far: 157709.2
Subtract 912 from 1270 to 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.

On to step 10:
3580 divided by 456 is 7 with a remainder of 388.
Put 7 as the next digit of the answer. 
Result so far: 157709.27
Subtracting 3192 from 3580 leaves us 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.

Going ahead to step 11:
456 goes into 3880 8 times with a remainder of 232.
The number 8 becomes the next digit in our result. 
Result so far: 157709.278
Subtract 3648 from 3880 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 12:
The number 456 fits into 2320 5 times, leaving a remainder of 40.
The next digit of our result is 5. 
Result so far: 157709.2785
Subtracting 2280 from 2320 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
If we divide 400 by 456, we get 0 and a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 157709.2785
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 14:
456 can be fit into 4000 8 times, resulting in a remainder of 352.
The number 8 becomes the next digit in our result. 
Result so far: 157709.278508
Subtracting 3648 from 4000 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 15:
3520 divided by 456 is 7 with a remainder of 328.
Record the quotient 7 as the next digit in the result. 
Result so far: 157709.2785087
If we subtract 3192 from 3520, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 16:
When dividing 3280 by 456, we get 7 with a remainder of 88.
The number 7 becomes the next digit in our result. 
Result so far: 157709.27850877
Subtracting 3192 from 3280 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final outcome is 157709.27850877, with a leftover of 8.8e-08.
