75240289 ÷ 346 
Our goal is to divide 75240289 by 346.

On to step 1:
When dividing 7 by 346, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 346

On to step 2:
When dividing 75 by 346, we get 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Grab the next digit (2) from the dividend, add it to 75, then carry on: 752 / 346

Step 3:
When dividing 752 by 346, we get 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 692 from 752 to get 60.
Append the next digit (4) from the dividend to 60 and continue with: 604 / 346

Advancing to step 4:
346 can be fit into 604 1 times, resulting in a remainder of 258.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 346 away from 604, we end up with 258.
Include the next digit (0) from the dividend after 258, then repeat: 2580 / 346

Advancing to step 5:
346 can be fit into 2580 7 times, resulting in a remainder of 158.
Record the quotient 7 as the next digit in the result. 
Result so far: 217.0
If we subtract 2422 from 2580, we get 158.
Append the next digit (2) from the dividend to 158 and continue with: 1582 / 346

Moving on to step 6:
346 can be fit into 1582 4 times, resulting in a remainder of 198.
Use 4 as the next digit of our solution. 
Result so far: 2174.0
If we subtract 1384 from 1582, we get 198.
Include the next digit (8) from the dividend after 198, then repeat: 1988 / 346

On to step 7:
346 goes into 1988 5 times with a remainder of 258.
Put 5 as the next digit of the answer. 
Result so far: 21745.0
Subtract 1730 from 1988 to get 258.
Append the next digit (9) from the dividend to 258 and continue with: 2589 / 346

Moving on to step 8:
346 can be fit into 2589 7 times, resulting in a remainder of 167.
Use 7 as the next digit of our solution. 
Result so far: 217457.0
The remainder is 167 after subtracting 2422 from 2589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Going ahead to step 9:
If we divide 1670 by 346, we get 4 and a remainder of 286.
The number 4 becomes the next digit in our result. 
Result so far: 217457.4
Deduct 1384 from 1670 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 10:
When dividing 2860 by 346, we get 8 with a remainder of 92.
Put 8 as the next digit of the answer. 
Result so far: 217457.48
If we take 2768 away from 2860, we end up with 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 11:
The number 346 fits into 920 2 times, leaving a remainder of 228.
Put 2 as the next digit of the answer. 
Result so far: 217457.482
Subtract 692 from 920 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 12:
If we divide 2280 by 346, we get 6 and a remainder of 204.
The number 6 becomes the next digit in our result. 
Result so far: 217457.4826
If we take 2076 away from 2280, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 13:
The number 346 fits into 2040 5 times, leaving a remainder of 310.
The next digit of our result is 5. 
Result so far: 217457.48265
If we take 1730 away from 2040, 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.

Going ahead to step 14:
3100 divided by 346 is 8 with a remainder of 332.
Put 8 as the next digit of the answer. 
Result so far: 217457.482658
If we take 2768 away from 3100, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 15:
The number 346 fits into 3320 9 times, leaving a remainder of 206.
Write down 9 as next digit of the result. 
Result so far: 217457.4826589
Deduct 3114 from 3320 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 16:
If we divide 2060 by 346, we get 5 and a remainder of 330.
Put 5 as the next digit of the answer. 
Result so far: 217457.48265895
The remainder is 330 after subtracting 1730 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

In conclusion, the division gives 217457.48265895 with a balance of 3.3e-07.
