75144723 divided by 388 
We want to figure out the number of times 75144723 can be divided by 388.

On to step 1:
7 divided by 388 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 388

Moving on to step 2:
75 divided by 388 is 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Take the next digit (1) from the dividend and append it to 75, then repeat: 751 / 388

Moving on to step 3:
388 can be fit into 751 1 times, resulting in a remainder of 363.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 388 from 751 to get 363.
Bring next digit (4) of the dividend behind the 363 and repeat the process: 3634 / 388

Moving on to step 4:
388 can be fit into 3634 9 times, resulting in a remainder of 142.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 142 after subtracting 3492 from 3634.
Append the next digit (4) from the dividend to 142 and continue with: 1424 / 388

Advancing to step 5:
388 can be fit into 1424 3 times, resulting in a remainder of 260.
Put 3 as the next digit of the answer. 
Result so far: 193.0
If we take 1164 away from 1424, we end up with 260.
Grab the next digit (7) from the dividend, add it to 260, then carry on: 2607 / 388

Advancing to step 6:
If we divide 2607 by 388, we get 6 and a remainder of 279.
Record the quotient 6 as the next digit in the result. 
Result so far: 1936.0
If we subtract 2328 from 2607, we get 279.
Include the next digit (2) from the dividend after 279, then repeat: 2792 / 388

Advancing to step 7:
When dividing 2792 by 388, we get 7 with a remainder of 76.
The number 7 becomes the next digit in our result. 
Result so far: 19367.0
The remainder is 76 after subtracting 2716 from 2792.
Take the next digit (3) from the dividend and append it to 76, then repeat: 763 / 388

Advancing to step 8:
When dividing 763 by 388, we get 1 with a remainder of 375.
The number 1 becomes the next digit in our result. 
Result so far: 193671.0
The remainder is 375 after subtracting 388 from 763.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 9:
When dividing 3750 by 388, we get 9 with a remainder of 258.
The number 9 becomes the next digit in our result. 
Result so far: 193671.9
Subtract 3492 from 3750 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 10:
388 goes into 2580 6 times with a remainder of 252.
Record the quotient 6 as the next digit in the result. 
Result so far: 193671.96
Subtracting 2328 from 2580 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 11:
388 goes into 2520 6 times with a remainder of 192.
Use 6 as the next digit of our solution. 
Result so far: 193671.966
If we take 2328 away from 2520, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The final outcome is 193671.966, with a leftover of 0.0192.
