76188673 ÷ 345 
Our goal is to divide 76188673 by 345.

Step 1:
7 divided by 345 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 345

Going ahead to step 2:
345 goes into 76 0 times with a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Bring next digit (1) of the dividend behind the 76 and repeat the process: 761 / 345

Let's proceed to step 3:
345 can be fit into 761 2 times, resulting in a remainder of 71.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 690 from 761 to get 71.
Fetch the next digit (8) from the dividend, attach it to 71 and continue: 718 / 345

Advancing to step 4:
718 divided by 345 is 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 690 from 718 to get 28.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 345

On to step 5:
288 divided by 345 is 0 with a remainder of 288.
The next digit of our result is 0. 
Result so far: 220.0
Subtract 0 from 288 to get 288.
Take the next digit (6) from the dividend and append it to 288, then repeat: 2886 / 345

Advancing to step 6:
345 can be fit into 2886 8 times, resulting in a remainder of 126.
The next digit of our result is 8. 
Result so far: 2208.0
Subtract 2760 from 2886 to get 126.
Append the next digit (7) from the dividend to 126 and continue with: 1267 / 345

On to step 7:
The number 345 fits into 1267 3 times, leaving a remainder of 232.
The number 3 becomes the next digit in our result. 
Result so far: 22083.0
The remainder is 232 after subtracting 1035 from 1267.
Fetch the next digit (3) from the dividend, attach it to 232 and continue: 2323 / 345

Advancing to step 8:
345 goes into 2323 6 times with a remainder of 253.
The number 6 becomes the next digit in our result. 
Result so far: 220836.0
If we subtract 2070 from 2323, we get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Advancing to step 9:
If we divide 2530 by 345, we get 7 and a remainder of 115.
The number 7 becomes the next digit in our result. 
Result so far: 220836.7
If we subtract 2415 from 2530, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 10:
The number 345 fits into 1150 3 times, leaving a remainder of 115.
Write down 3 as next digit of the result. 
Result so far: 220836.73
If we take 1035 away from 1150, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 11:
When dividing 1150 by 345, we get 3 with a remainder of 115.
Record the quotient 3 as the next digit in the result. 
Result so far: 220836.733
Subtract 1035 from 1150 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

The final result is 220836.733 with a remainder of 0.0115.
