378174 divided by 346 
Our goal is to divide 378174 by 346.

On to step 1:
3 divided by 346 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 346

Advancing to step 2:
346 goes into 37 0 times with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 346

On to step 3:
346 goes into 378 1 times with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 346 from 378 to get 32.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 346

On to step 4:
The number 346 fits into 321 0 times, leaving a remainder of 321.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 321, we get 321.
Include the next digit (7) from the dividend after 321, then repeat: 3217 / 346

Let's proceed to step 5:
3217 divided by 346 is 9 with a remainder of 103.
Put 9 as the next digit of the answer. 
Result so far: 109.0
If we subtract 3114 from 3217, we get 103.
Append the next digit (4) from the dividend to 103 and continue with: 1034 / 346

Going ahead to step 6:
The number 346 fits into 1034 2 times, leaving a remainder of 342.
The next digit of our result is 2. 
Result so far: 1092.0
If we take 692 away from 1034, we end up with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Moving on to step 7:
346 goes into 3420 9 times with a remainder of 306.
Write down 9 as next digit of the result. 
Result so far: 1092.9
Deduct 3114 from 3420 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 8:
346 goes into 3060 8 times with a remainder of 292.
Write down 8 as next digit of the result. 
Result so far: 1092.98
Subtracting 2768 from 3060 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 9:
2920 divided by 346 is 8 with a remainder of 152.
Write down 8 as next digit of the result. 
Result so far: 1092.988
Subtracting 2768 from 2920 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

The final outcome is 1092.988, with a leftover of 0.0152.
