13360538 ÷ 423 
We want to divide 13360538 by 423.

Going ahead to step 1:
When dividing 1 by 423, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 423

Let's proceed to step 2:
When dividing 13 by 423, we get 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 423

Step 3:
423 can be fit into 133 0 times, resulting in a remainder of 133.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 133, we end up with 133.
Append the next digit (6) from the dividend to 133 and continue with: 1336 / 423

Let's proceed to step 4:
1336 divided by 423 is 3 with a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 1269 away from 1336, we end up with 67.
Fetch the next digit (0) from the dividend, attach it to 67 and continue: 670 / 423

On to step 5:
When dividing 670 by 423, we get 1 with a remainder of 247.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Deduct 423 from 670 and we're left with 247.
Append the next digit (5) from the dividend to 247 and continue with: 2475 / 423

Advancing to step 6:
The number 423 fits into 2475 5 times, leaving a remainder of 360.
Record the quotient 5 as the next digit in the result. 
Result so far: 315.0
The remainder is 360 after subtracting 2115 from 2475.
Bring next digit (3) of the dividend behind the 360 and repeat the process: 3603 / 423

Step 7:
423 can be fit into 3603 8 times, resulting in a remainder of 219.
Use 8 as the next digit of our solution. 
Result so far: 3158.0
Subtract 3384 from 3603 to get 219.
Fetch the next digit (8) from the dividend, attach it to 219 and continue: 2198 / 423

Let's proceed to step 8:
If we divide 2198 by 423, we get 5 and a remainder of 83.
Record the quotient 5 as the next digit in the result. 
Result so far: 31585.0
Subtract 2115 from 2198 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 9:
When dividing 830 by 423, we get 1 with a remainder of 407.
The number 1 becomes the next digit in our result. 
Result so far: 31585.1
Subtract 423 from 830 to get 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

On to step 10:
If we divide 4070 by 423, we get 9 and a remainder of 263.
The number 9 becomes the next digit in our result. 
Result so far: 31585.19
If we take 3807 away from 4070, we end up with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Step 11:
2630 divided by 423 is 6 with a remainder of 92.
Write down 6 as next digit of the result. 
Result so far: 31585.196
Subtract 2538 from 2630 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 12:
If we divide 920 by 423, we get 2 and a remainder of 74.
Put 2 as the next digit of the answer. 
Result so far: 31585.1962
Subtracting 846 from 920 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 13:
740 divided by 423 is 1 with a remainder of 317.
Record the quotient 1 as the next digit in the result. 
Result so far: 31585.19621
Subtracting 423 from 740 leaves us with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Moving on to step 14:
If we divide 3170 by 423, we get 7 and a remainder of 209.
The number 7 becomes the next digit in our result. 
Result so far: 31585.196217
If we take 2961 away from 3170, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 15:
423 can be fit into 2090 4 times, resulting in a remainder of 398.
Record the quotient 4 as the next digit in the result. 
Result so far: 31585.1962174
The remainder is 398 after subtracting 1692 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Advancing to step 16:
If we divide 3980 by 423, we get 9 and a remainder of 173.
The next digit of our result is 9. 
Result so far: 31585.19621749
If we take 3807 away from 3980, we end up with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

The final outcome is 31585.19621749, with a leftover of 1.73e-07.
