Let's divide 17238310 by 408
We're looking to find how many times 408 goes into 17238310.

Advancing to step 1:
The number 408 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 408

Let's proceed to step 2:
17 divided by 408 is 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 408

Going ahead to step 3:
408 can be fit into 172 0 times, resulting in a remainder of 172.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 172, we end up with 172.
Fetch the next digit (3) from the dividend, attach it to 172 and continue: 1723 / 408

Advancing to step 4:
The number 408 fits into 1723 4 times, leaving a remainder of 91.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 1632 from 1723 and we're left with 91.
Append the next digit (8) from the dividend to 91 and continue with: 918 / 408

Advancing to step 5:
The number 408 fits into 918 2 times, leaving a remainder of 102.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtract 816 from 918 to get 102.
Fetch the next digit (3) from the dividend, attach it to 102 and continue: 1023 / 408

Step 6:
1023 divided by 408 is 2 with a remainder of 207.
The number 2 becomes the next digit in our result. 
Result so far: 422.0
Subtracting 816 from 1023 leaves us with 207.
Take the next digit (1) from the dividend and append it to 207, then repeat: 2071 / 408

Going ahead to step 7:
The number 408 fits into 2071 5 times, leaving a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 4225.0
The remainder is 31 after subtracting 2040 from 2071.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 408

On to step 8:
When dividing 310 by 408, we get 0 with a remainder of 310.
The number 0 becomes the next digit in our result. 
Result so far: 42250.0
If we take 0 away from 310, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 9:
408 can be fit into 3100 7 times, resulting in a remainder of 244.
Write down 7 as next digit of the result. 
Result so far: 42250.7
Subtracting 2856 from 3100 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 10:
If we divide 2440 by 408, we get 5 and a remainder of 400.
Record the quotient 5 as the next digit in the result. 
Result so far: 42250.75
If we subtract 2040 from 2440, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 11:
The number 408 fits into 4000 9 times, leaving a remainder of 328.
The number 9 becomes the next digit in our result. 
Result so far: 42250.759
Subtract 3672 from 4000 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 12:
If we divide 3280 by 408, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 42250.7598
Subtracting 3264 from 3280 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
408 can be fit into 160 0 times, resulting in a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 42250.7598
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
408 can be fit into 1600 3 times, resulting in a remainder of 376.
Use 3 as the next digit of our solution. 
Result so far: 42250.759803
If we subtract 1224 from 1600, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 15:
If we divide 3760 by 408, we get 9 and a remainder of 88.
Use 9 as the next digit of our solution. 
Result so far: 42250.7598039
If we take 3672 away from 3760, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 16:
880 divided by 408 is 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 42250.75980392
Subtract 816 from 880 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 42250.75980392, with a leftover of 6.4e-08.
