We're dividing 37974302 by 345 
We're looking to find how many times 345 goes into 37974302.

On to step 1:
The number 345 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 345

On to step 2:
345 goes into 37 0 times with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 345

Step 3:
345 goes into 379 1 times with a remainder of 34.
The next digit of our result is 1. 
Result so far: 1.0
If we take 345 away from 379, we end up with 34.
Grab the next digit (7) from the dividend, add it to 34, then carry on: 347 / 345

Step 4:
347 divided by 345 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 345 from 347 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 345

On to step 5:
345 can be fit into 24 0 times, resulting in a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 110.0
If we take 0 away from 24, we end up with 24.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 345

Advancing to step 6:
If we divide 243 by 345, we get 0 and a remainder of 243.
Write down 0 as next digit of the result. 
Result so far: 1100.0
Deduct 0 from 243 and we're left with 243.
Take the next digit (0) from the dividend and append it to 243, then repeat: 2430 / 345

Moving on to step 7:
345 can be fit into 2430 7 times, resulting in a remainder of 15.
The next digit of our result is 7. 
Result so far: 11007.0
The remainder is 15 after subtracting 2415 from 2430.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 345

Step 8:
152 divided by 345 is 0 with a remainder of 152.
The number 0 becomes the next digit in our result. 
Result so far: 110070.0
If we subtract 0 from 152, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 9:
If we divide 1520 by 345, we get 4 and a remainder of 140.
The number 4 becomes the next digit in our result. 
Result so far: 110070.4
The remainder is 140 after subtracting 1380 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
1400 divided by 345 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 110070.44
The remainder is 20 after subtracting 1380 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 110070.44 with a balance of 0.02.
