We look at the division of 34500040 by 423 
Let's see how many times 423 fits into 34500040.

Moving on to step 1:
423 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 423

Moving on to step 2:
423 goes into 34 0 times with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 423

Moving on to step 3:
345 divided by 423 is 0 with a remainder of 345.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 345 and we're left with 345.
Bring next digit (0) of the dividend behind the 345 and repeat the process: 3450 / 423

Moving on to step 4:
423 can be fit into 3450 8 times, resulting in a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 3384 from 3450 to get 66.
Bring next digit (0) of the dividend behind the 66 and repeat the process: 660 / 423

Let's proceed to step 5:
If we divide 660 by 423, we get 1 and a remainder of 237.
Use 1 as the next digit of our solution. 
Result so far: 81.0
The remainder is 237 after subtracting 423 from 660.
Bring next digit (0) of the dividend behind the 237 and repeat the process: 2370 / 423

On to step 6:
The number 423 fits into 2370 5 times, leaving a remainder of 255.
Use 5 as the next digit of our solution. 
Result so far: 815.0
Subtract 2115 from 2370 to get 255.
Bring next digit (4) of the dividend behind the 255 and repeat the process: 2554 / 423

Moving on to step 7:
The number 423 fits into 2554 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 8156.0
If we subtract 2538 from 2554, we get 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 423

On to step 8:
If we divide 160 by 423, we get 0 and a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 81560.0
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 9:
The number 423 fits into 1600 3 times, leaving a remainder of 331.
The next digit of our result is 3. 
Result so far: 81560.3
Subtract 1269 from 1600 to get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Let's proceed to step 10:
3310 divided by 423 is 7 with a remainder of 349.
Put 7 as the next digit of the answer. 
Result so far: 81560.37
The remainder is 349 after subtracting 2961 from 3310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Let's proceed to step 11:
423 can be fit into 3490 8 times, resulting in a remainder of 106.
The number 8 becomes the next digit in our result. 
Result so far: 81560.378
If we subtract 3384 from 3490, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 12:
1060 divided by 423 is 2 with a remainder of 214.
Write down 2 as next digit of the result. 
Result so far: 81560.3782
Subtracting 846 from 1060 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 13:
If we divide 2140 by 423, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 81560.37825
Subtracting 2115 from 2140 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 14:
The number 423 fits into 250 0 times, leaving a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 81560.37825
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 15:
423 goes into 2500 5 times with a remainder of 385.
The number 5 becomes the next digit in our result. 
Result so far: 81560.3782505
The remainder is 385 after subtracting 2115 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Going ahead to step 16:
The number 423 fits into 3850 9 times, leaving a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 81560.37825059
Subtracting 3807 from 3850 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final result is 81560.37825059 with a remainder of 4.3e-08.
