71074143 ÷ 458 
We want to figure out the number of times 71074143 can be divided by 458.

On to step 1:
7 divided by 458 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 458

Step 2:
71 divided by 458 is 0 with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Fetch the next digit (0) from the dividend, attach it to 71 and continue: 710 / 458

Going ahead to step 3:
710 divided by 458 is 1 with a remainder of 252.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 252 after subtracting 458 from 710.
Take the next digit (7) from the dividend and append it to 252, then repeat: 2527 / 458

Moving on to step 4:
2527 divided by 458 is 5 with a remainder of 237.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 2290 from 2527, we get 237.
Append the next digit (4) from the dividend to 237 and continue with: 2374 / 458

On to step 5:
2374 divided by 458 is 5 with a remainder of 84.
Use 5 as the next digit of our solution. 
Result so far: 155.0
Subtract 2290 from 2374 to get 84.
Take the next digit (1) from the dividend and append it to 84, then repeat: 841 / 458

Going ahead to step 6:
The number 458 fits into 841 1 times, leaving a remainder of 383.
The next digit of our result is 1. 
Result so far: 1551.0
Subtracting 458 from 841 leaves us with 383.
Fetch the next digit (4) from the dividend, attach it to 383 and continue: 3834 / 458

Step 7:
When dividing 3834 by 458, we get 8 with a remainder of 170.
Use 8 as the next digit of our solution. 
Result so far: 15518.0
Subtracting 3664 from 3834 leaves us with 170.
Grab the next digit (3) from the dividend, add it to 170, then carry on: 1703 / 458

Going ahead to step 8:
458 goes into 1703 3 times with a remainder of 329.
Use 3 as the next digit of our solution. 
Result so far: 155183.0
If we take 1374 away from 1703, we end up with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

On to step 9:
If we divide 3290 by 458, we get 7 and a remainder of 84.
Write down 7 as next digit of the result. 
Result so far: 155183.7
Deduct 3206 from 3290 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 10:
When dividing 840 by 458, we get 1 with a remainder of 382.
The next digit of our result is 1. 
Result so far: 155183.71
The remainder is 382 after subtracting 458 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Moving on to step 11:
458 goes into 3820 8 times with a remainder of 156.
Write down 8 as next digit of the result. 
Result so far: 155183.718
Subtracting 3664 from 3820 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 12:
1560 divided by 458 is 3 with a remainder of 186.
Put 3 as the next digit of the answer. 
Result so far: 155183.7183
If we subtract 1374 from 1560, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 13:
1860 divided by 458 is 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 155183.71834
If we subtract 1832 from 1860, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
458 goes into 280 0 times with a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 155183.71834
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 15:
458 can be fit into 2800 6 times, resulting in a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 155183.7183406
The remainder is 52 after subtracting 2748 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 16:
458 goes into 520 1 times with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 155183.71834061
Subtracting 458 from 520 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

After the division, we end up with 155183.71834061 and a remainder of 6.2e-08.
