Let's divide 26399042 by 458
Our goal is to divide 26399042 by 458.

On to step 1:
The number 458 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 458

Going ahead to step 2:
If we divide 26 by 458, we get 0 and a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 458

Step 3:
If we divide 263 by 458, we get 0 and a remainder of 263.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 263 and we're left with 263.
Include the next digit (9) from the dividend after 263, then repeat: 2639 / 458

On to step 4:
When dividing 2639 by 458, we get 5 with a remainder of 349.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 2290 from 2639 and we're left with 349.
Take the next digit (9) from the dividend and append it to 349, then repeat: 3499 / 458

Going ahead to step 5:
458 can be fit into 3499 7 times, resulting in a remainder of 293.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Subtracting 3206 from 3499 leaves us with 293.
Fetch the next digit (0) from the dividend, attach it to 293 and continue: 2930 / 458

Step 6:
If we divide 2930 by 458, we get 6 and a remainder of 182.
Use 6 as the next digit of our solution. 
Result so far: 576.0
The remainder is 182 after subtracting 2748 from 2930.
Grab the next digit (4) from the dividend, add it to 182, then carry on: 1824 / 458

Moving on to step 7:
458 can be fit into 1824 3 times, resulting in a remainder of 450.
The number 3 becomes the next digit in our result. 
Result so far: 5763.0
Subtracting 1374 from 1824 leaves us with 450.
Grab the next digit (2) from the dividend, add it to 450, then carry on: 4502 / 458

Step 8:
458 goes into 4502 9 times with a remainder of 380.
Write down 9 as next digit of the result. 
Result so far: 57639.0
The remainder is 380 after subtracting 4122 from 4502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 9:
If we divide 3800 by 458, we get 8 and a remainder of 136.
Use 8 as the next digit of our solution. 
Result so far: 57639.8
The remainder is 136 after subtracting 3664 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 10:
The number 458 fits into 1360 2 times, leaving a remainder of 444.
The next digit of our result is 2. 
Result so far: 57639.82
Subtracting 916 from 1360 leaves us with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

On to step 11:
4440 divided by 458 is 9 with a remainder of 318.
Write down 9 as next digit of the result. 
Result so far: 57639.829
Subtract 4122 from 4440 to get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 12:
458 can be fit into 3180 6 times, resulting in a remainder of 432.
Record the quotient 6 as the next digit in the result. 
Result so far: 57639.8296
Deduct 2748 from 3180 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 13:
458 goes into 4320 9 times with a remainder of 198.
Write down 9 as next digit of the result. 
Result so far: 57639.82969
The remainder is 198 after subtracting 4122 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Let's proceed to step 14:
The number 458 fits into 1980 4 times, leaving a remainder of 148.
Write down 4 as next digit of the result. 
Result so far: 57639.829694
Subtract 1832 from 1980 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 15:
1480 divided by 458 is 3 with a remainder of 106.
Put 3 as the next digit of the answer. 
Result so far: 57639.8296943
The remainder is 106 after subtracting 1374 from 1480.
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 16:
1060 divided by 458 is 2 with a remainder of 144.
The next digit of our result is 2. 
Result so far: 57639.82969432
The remainder is 144 after subtracting 916 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The final outcome is 57639.82969432, with a leftover of 1.44e-07.
