13000000 ÷ 345 
We're looking to find how many times 345 goes into 13000000.

Advancing to step 1:
When dividing 1 by 345, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 345

Going ahead to step 2:
345 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 345

Step 3:
If we divide 130 by 345, we get 0 and a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 130, we end up with 130.
Grab the next digit (0) from the dividend, add it to 130, then carry on: 1300 / 345

Advancing to step 4:
The number 345 fits into 1300 3 times, leaving a remainder of 265.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 1035 from 1300 to get 265.
Take the next digit (0) from the dividend and append it to 265, then repeat: 2650 / 345

On to step 5:
345 goes into 2650 7 times with a remainder of 235.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtract 2415 from 2650 to get 235.
Append the next digit (0) from the dividend to 235 and continue with: 2350 / 345

Going ahead to step 6:
The number 345 fits into 2350 6 times, leaving a remainder of 280.
Use 6 as the next digit of our solution. 
Result so far: 376.0
Subtract 2070 from 2350 to get 280.
Append the next digit (0) from the dividend to 280 and continue with: 2800 / 345

On to step 7:
If we divide 2800 by 345, we get 8 and a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 3768.0
Subtract 2760 from 2800 to get 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 345

Advancing to step 8:
345 can be fit into 400 1 times, resulting in a remainder of 55.
The next digit of our result is 1. 
Result so far: 37681.0
Subtract 345 from 400 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 9:
345 goes into 550 1 times with a remainder of 205.
The number 1 becomes the next digit in our result. 
Result so far: 37681.1
Deduct 345 from 550 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 10:
If we divide 2050 by 345, we get 5 and a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 37681.15
Deduct 1725 from 2050 and we're left with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 11:
When dividing 3250 by 345, we get 9 with a remainder of 145.
The next digit of our result is 9. 
Result so far: 37681.159
If we take 3105 away from 3250, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 12:
If we divide 1450 by 345, we get 4 and a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 37681.1594
If we take 1380 away from 1450, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 13:
345 can be fit into 700 2 times, resulting in a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 37681.15942
Subtract 690 from 700 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
When dividing 100 by 345, we get 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 37681.15942
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 15:
When dividing 1000 by 345, we get 2 with a remainder of 310.
Record the quotient 2 as the next digit in the result. 
Result so far: 37681.1594202
If we subtract 690 from 1000, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 16:
3100 divided by 345 is 8 with a remainder of 340.
Write down 8 as next digit of the result. 
Result so far: 37681.15942028
Deduct 2760 from 3100 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The final outcome is 37681.15942028, with a leftover of 3.4e-07.
