39543158 divided by 378 
Our goal is to divide 39543158 by 378.

Going ahead to step 1:
The number 378 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
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 378

Advancing to step 2:
If we divide 39 by 378, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 378

Going ahead to step 3:
If we divide 395 by 378, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 378 from 395, we get 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 378

Let's proceed to step 4:
174 divided by 378 is 0 with a remainder of 174.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 174 to get 174.
Take the next digit (3) from the dividend and append it to 174, then repeat: 1743 / 378

Moving on to step 5:
If we divide 1743 by 378, we get 4 and a remainder of 231.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
Subtracting 1512 from 1743 leaves us with 231.
Append the next digit (1) from the dividend to 231 and continue with: 2311 / 378

Step 6:
When dividing 2311 by 378, we get 6 with a remainder of 43.
Write down 6 as next digit of the result. 
Result so far: 1046.0
Subtract 2268 from 2311 to get 43.
Grab the next digit (5) from the dividend, add it to 43, then carry on: 435 / 378

Step 7:
If we divide 435 by 378, we get 1 and a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 10461.0
Deduct 378 from 435 and we're left with 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 378

Advancing to step 8:
378 goes into 578 1 times with a remainder of 200.
Put 1 as the next digit of the answer. 
Result so far: 104611.0
Deduct 378 from 578 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 9:
378 goes into 2000 5 times with a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 104611.5
Deduct 1890 from 2000 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
When dividing 1100 by 378, we get 2 with a remainder of 344.
The next digit of our result is 2. 
Result so far: 104611.52
Subtract 756 from 1100 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 11:
378 goes into 3440 9 times with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 104611.529
Subtract 3402 from 3440 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
If we divide 380 by 378, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 104611.5291
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
20 divided by 378 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 104611.5291
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
The number 378 fits into 200 0 times, leaving a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 104611.5291
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Our division results in 104611.5291 with a remaining 2e-05.
