40253127 ÷ 458 
We want to figure out the number of times 40253127 can be divided by 458.

Advancing to step 1:
When dividing 4 by 458, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 458

Going ahead to step 2:
When dividing 40 by 458, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Bring next digit (2) of the dividend behind the 40 and repeat the process: 402 / 458

Advancing to step 3:
When dividing 402 by 458, we get 0 with a remainder of 402.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 402, we get 402.
Include the next digit (5) from the dividend after 402, then repeat: 4025 / 458

Going ahead to step 4:
If we divide 4025 by 458, we get 8 and a remainder of 361.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 3664 from 4025 leaves us with 361.
Include the next digit (3) from the dividend after 361, then repeat: 3613 / 458

Going ahead to step 5:
If we divide 3613 by 458, we get 7 and a remainder of 407.
Put 7 as the next digit of the answer. 
Result so far: 87.0
Deduct 3206 from 3613 and we're left with 407.
Bring next digit (1) of the dividend behind the 407 and repeat the process: 4071 / 458

On to step 6:
4071 divided by 458 is 8 with a remainder of 407.
The number 8 becomes the next digit in our result. 
Result so far: 878.0
If we take 3664 away from 4071, we end up with 407.
Fetch the next digit (2) from the dividend, attach it to 407 and continue: 4072 / 458

Advancing to step 7:
4072 divided by 458 is 8 with a remainder of 408.
Use 8 as the next digit of our solution. 
Result so far: 8788.0
If we take 3664 away from 4072, we end up with 408.
Fetch the next digit (7) from the dividend, attach it to 408 and continue: 4087 / 458

Moving on to step 8:
4087 divided by 458 is 8 with a remainder of 423.
The number 8 becomes the next digit in our result. 
Result so far: 87888.0
The remainder is 423 after subtracting 3664 from 4087.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Advancing to step 9:
458 goes into 4230 9 times with a remainder of 108.
Put 9 as the next digit of the answer. 
Result so far: 87888.9
Subtract 4122 from 4230 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 10:
If we divide 1080 by 458, we get 2 and a remainder of 164.
Put 2 as the next digit of the answer. 
Result so far: 87888.92
If we subtract 916 from 1080, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 11:
When dividing 1640 by 458, we get 3 with a remainder of 266.
Use 3 as the next digit of our solution. 
Result so far: 87888.923
Deduct 1374 from 1640 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 12:
When dividing 2660 by 458, we get 5 with a remainder of 370.
Put 5 as the next digit of the answer. 
Result so far: 87888.9235
If we take 2290 away from 2660, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 13:
When dividing 3700 by 458, we get 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 87888.92358
Deduct 3664 from 3700 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 14:
The number 458 fits into 360 0 times, leaving a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 87888.92358
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 15:
458 can be fit into 3600 7 times, resulting in a remainder of 394.
The number 7 becomes the next digit in our result. 
Result so far: 87888.9235807
Deduct 3206 from 3600 and we're left with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

On to step 16:
When dividing 3940 by 458, we get 8 with a remainder of 276.
The next digit of our result is 8. 
Result so far: 87888.92358078
If we take 3664 away from 3940, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

The quotient of the division is 87888.92358078, and the remainder is 2.76e-07.
