46752123 ÷ 345 
Let's see how many times 345 fits into 46752123.

Step 1:
The number 345 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 345

On to step 2:
345 goes into 46 0 times with a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 46, we end up with 46.
Bring next digit (7) of the dividend behind the 46 and repeat the process: 467 / 345

Going ahead to step 3:
The number 345 fits into 467 1 times, leaving a remainder of 122.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 122 after subtracting 345 from 467.
Grab the next digit (5) from the dividend, add it to 122, then carry on: 1225 / 345

Going ahead to step 4:
The number 345 fits into 1225 3 times, leaving a remainder of 190.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 1035 away from 1225, we end up with 190.
Append the next digit (2) from the dividend to 190 and continue with: 1902 / 345

On to step 5:
345 goes into 1902 5 times with a remainder of 177.
Write down 5 as next digit of the result. 
Result so far: 135.0
Subtract 1725 from 1902 to get 177.
Include the next digit (1) from the dividend after 177, then repeat: 1771 / 345

Let's proceed to step 6:
345 can be fit into 1771 5 times, resulting in a remainder of 46.
Write down 5 as next digit of the result. 
Result so far: 1355.0
If we take 1725 away from 1771, we end up with 46.
Append the next digit (2) from the dividend to 46 and continue with: 462 / 345

Moving on to step 7:
The number 345 fits into 462 1 times, leaving a remainder of 117.
Use 1 as the next digit of our solution. 
Result so far: 13551.0
Subtracting 345 from 462 leaves us with 117.
Append the next digit (3) from the dividend to 117 and continue with: 1173 / 345

Advancing to step 8:
The number 345 fits into 1173 3 times, leaving a remainder of 138.
The number 3 becomes the next digit in our result. 
Result so far: 135513.0
Deduct 1035 from 1173 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 9:
1380 divided by 345 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 135513.4
Subtracting 1380 from 1380 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
When dividing 0 by 345, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 135513.4
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
345 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 135513.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 135513.4 with a remainder of 0.0.
