We look at the division of 25142842 by 423 
We're looking to find how many times 423 goes into 25142842.

Moving on to step 1:
423 can be fit into 2 0 times, resulting in 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.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 423

Going ahead to step 2:
If we divide 25 by 423, we get 0 and a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 423

Advancing to step 3:
423 goes into 251 0 times with a remainder of 251.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 251 and we're left with 251.
Take the next digit (4) from the dividend and append it to 251, then repeat: 2514 / 423

Moving on to step 4:
If we divide 2514 by 423, we get 5 and a remainder of 399.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 2115 from 2514 to get 399.
Include the next digit (2) from the dividend after 399, then repeat: 3992 / 423

Going ahead to step 5:
3992 divided by 423 is 9 with a remainder of 185.
Use 9 as the next digit of our solution. 
Result so far: 59.0
Deduct 3807 from 3992 and we're left with 185.
Append the next digit (8) from the dividend to 185 and continue with: 1858 / 423

On to step 6:
1858 divided by 423 is 4 with a remainder of 166.
Use 4 as the next digit of our solution. 
Result so far: 594.0
If we subtract 1692 from 1858, we get 166.
Take the next digit (4) from the dividend and append it to 166, then repeat: 1664 / 423

Step 7:
When dividing 1664 by 423, we get 3 with a remainder of 395.
Write down 3 as next digit of the result. 
Result so far: 5943.0
Subtracting 1269 from 1664 leaves us with 395.
Take the next digit (2) from the dividend and append it to 395, then repeat: 3952 / 423

Step 8:
When dividing 3952 by 423, we get 9 with a remainder of 145.
Put 9 as the next digit of the answer. 
Result so far: 59439.0
The remainder is 145 after subtracting 3807 from 3952.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 9:
The number 423 fits into 1450 3 times, leaving a remainder of 181.
Record the quotient 3 as the next digit in the result. 
Result so far: 59439.3
Deduct 1269 from 1450 and we're left with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 10:
The number 423 fits into 1810 4 times, leaving a remainder of 118.
Write down 4 as next digit of the result. 
Result so far: 59439.34
The remainder is 118 after subtracting 1692 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 11:
423 goes into 1180 2 times with a remainder of 334.
Write down 2 as next digit of the result. 
Result so far: 59439.342
The remainder is 334 after subtracting 846 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Moving on to step 12:
423 can be fit into 3340 7 times, resulting in a remainder of 379.
The number 7 becomes the next digit in our result. 
Result so far: 59439.3427
Subtract 2961 from 3340 to get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

On to step 13:
423 goes into 3790 8 times with a remainder of 406.
The number 8 becomes the next digit in our result. 
Result so far: 59439.34278
If we take 3384 away from 3790, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

On to step 14:
The number 423 fits into 4060 9 times, leaving a remainder of 253.
The number 9 becomes the next digit in our result. 
Result so far: 59439.342789
Subtracting 3807 from 4060 leaves us with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Going ahead to step 15:
When dividing 2530 by 423, we get 5 with a remainder of 415.
The number 5 becomes the next digit in our result. 
Result so far: 59439.3427895
Subtract 2115 from 2530 to get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Moving on to step 16:
When dividing 4150 by 423, we get 9 with a remainder of 343.
Record the quotient 9 as the next digit in the result. 
Result so far: 59439.34278959
Deduct 3807 from 4150 and we're left with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

The final outcome is 59439.34278959, with a leftover of 3.43e-07.
