75380170 ÷ 257 
We want to divide 75380170 by 257.

Advancing to step 1:
When dividing 7 by 257, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 257

Going ahead to step 2:
If we divide 75 by 257, we get 0 and a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Take the next digit (3) from the dividend and append it to 75, then repeat: 753 / 257

On to step 3:
The number 257 fits into 753 2 times, leaving a remainder of 239.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 514 away from 753, we end up with 239.
Append the next digit (8) from the dividend to 239 and continue with: 2398 / 257

On to step 4:
If we divide 2398 by 257, we get 9 and a remainder of 85.
The next digit of our result is 9. 
Result so far: 29.0
If we subtract 2313 from 2398, we get 85.
Bring next digit (0) of the dividend behind the 85 and repeat the process: 850 / 257

Advancing to step 5:
When dividing 850 by 257, we get 3 with a remainder of 79.
Use 3 as the next digit of our solution. 
Result so far: 293.0
Subtracting 771 from 850 leaves us with 79.
Take the next digit (1) from the dividend and append it to 79, then repeat: 791 / 257

Going ahead to step 6:
791 divided by 257 is 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 2933.0
Subtracting 771 from 791 leaves us with 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 257

Going ahead to step 7:
257 can be fit into 207 0 times, resulting in a remainder of 207.
Record the quotient 0 as the next digit in the result. 
Result so far: 29330.0
The remainder is 207 after subtracting 0 from 207.
Grab the next digit (0) from the dividend, add it to 207, then carry on: 2070 / 257

Moving on to step 8:
2070 divided by 257 is 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 293308.0
Subtracting 2056 from 2070 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
257 goes into 140 0 times with a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 293308.0
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
1400 divided by 257 is 5 with a remainder of 115.
The next digit of our result is 5. 
Result so far: 293308.05
The remainder is 115 after subtracting 1285 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 11:
When dividing 1150 by 257, we get 4 with a remainder of 122.
The next digit of our result is 4. 
Result so far: 293308.054
If we subtract 1028 from 1150, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 12:
When dividing 1220 by 257, we get 4 with a remainder of 192.
Put 4 as the next digit of the answer. 
Result so far: 293308.0544
If we take 1028 away from 1220, 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.

Our division results in 293308.0544 with a remaining 0.00192.
