75338771 ÷ 390 
We want to divide 75338771 by 390.

Going ahead to step 1:
If we divide 7 by 390, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 390

Moving on to step 2:
390 can be fit into 75 0 times, resulting in a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Fetch the next digit (3) from the dividend, attach it to 75 and continue: 753 / 390

Advancing to step 3:
If we divide 753 by 390, we get 1 and a remainder of 363.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 390 away from 753, we end up with 363.
Append the next digit (3) from the dividend to 363 and continue with: 3633 / 390

On to step 4:
390 goes into 3633 9 times with a remainder of 123.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 3510 from 3633, we get 123.
Bring next digit (8) of the dividend behind the 123 and repeat the process: 1238 / 390

Advancing to step 5:
390 can be fit into 1238 3 times, resulting in a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 193.0
Subtract 1170 from 1238 to get 68.
Grab the next digit (7) from the dividend, add it to 68, then carry on: 687 / 390

On to step 6:
687 divided by 390 is 1 with a remainder of 297.
Write down 1 as next digit of the result. 
Result so far: 1931.0
Subtracting 390 from 687 leaves us with 297.
Bring next digit (7) of the dividend behind the 297 and repeat the process: 2977 / 390

Advancing to step 7:
The number 390 fits into 2977 7 times, leaving a remainder of 247.
Use 7 as the next digit of our solution. 
Result so far: 19317.0
The remainder is 247 after subtracting 2730 from 2977.
Include the next digit (1) from the dividend after 247, then repeat: 2471 / 390

Advancing to step 8:
390 can be fit into 2471 6 times, resulting in a remainder of 131.
Use 6 as the next digit of our solution. 
Result so far: 193176.0
If we take 2340 away from 2471, we end up with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 9:
390 goes into 1310 3 times with a remainder of 140.
Use 3 as the next digit of our solution. 
Result so far: 193176.3
Subtract 1170 from 1310 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 10:
390 can be fit into 1400 3 times, resulting in a remainder of 230.
Put 3 as the next digit of the answer. 
Result so far: 193176.33
Deduct 1170 from 1400 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

After the division, we end up with 193176.33 and a remainder of 0.23.
