Let's divide 78435749 by 345
Our goal is to divide 78435749 by 345.

Step 1:
7 divided by 345 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 345

Let's proceed to step 2:
When dividing 78 by 345, we get 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (4) from the dividend, add it to 78, then carry on: 784 / 345

Advancing to step 3:
784 divided by 345 is 2 with a remainder of 94.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 94 after subtracting 690 from 784.
Append the next digit (3) from the dividend to 94 and continue with: 943 / 345

Step 4:
345 can be fit into 943 2 times, resulting in a remainder of 253.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 690 from 943, we get 253.
Include the next digit (5) from the dividend after 253, then repeat: 2535 / 345

Going ahead to step 5:
2535 divided by 345 is 7 with a remainder of 120.
Write down 7 as next digit of the result. 
Result so far: 227.0
Subtract 2415 from 2535 to get 120.
Take the next digit (7) from the dividend and append it to 120, then repeat: 1207 / 345

Moving on to step 6:
If we divide 1207 by 345, we get 3 and a remainder of 172.
Use 3 as the next digit of our solution. 
Result so far: 2273.0
If we subtract 1035 from 1207, we get 172.
Include the next digit (4) from the dividend after 172, then repeat: 1724 / 345

Going ahead to step 7:
The number 345 fits into 1724 4 times, leaving a remainder of 344.
The number 4 becomes the next digit in our result. 
Result so far: 22734.0
Deduct 1380 from 1724 and we're left with 344.
Append the next digit (9) from the dividend to 344 and continue with: 3449 / 345

Let's proceed to step 8:
The number 345 fits into 3449 9 times, leaving a remainder of 344.
Put 9 as the next digit of the answer. 
Result so far: 227349.0
Deduct 3105 from 3449 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 9:
3440 divided by 345 is 9 with a remainder of 335.
Use 9 as the next digit of our solution. 
Result so far: 227349.9
Subtracting 3105 from 3440 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 10:
When dividing 3350 by 345, we get 9 with a remainder of 245.
Use 9 as the next digit of our solution. 
Result so far: 227349.99
If we take 3105 away from 3350, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

In conclusion, the division gives 227349.99 with a balance of 0.245.
