Let's divide 2631557 by 378
We want to divide 2631557 by 378.

Step 1:
378 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 378

Let's proceed to step 2:
378 goes into 26 0 times with a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 378

Advancing to step 3:
If we divide 263 by 378, we get 0 and a remainder of 263.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 263 and we're left with 263.
Fetch the next digit (1) from the dividend, attach it to 263 and continue: 2631 / 378

Going ahead to step 4:
378 can be fit into 2631 6 times, resulting in a remainder of 363.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 2268 from 2631 and we're left with 363.
Append the next digit (5) from the dividend to 363 and continue with: 3635 / 378

Step 5:
378 can be fit into 3635 9 times, resulting in a remainder of 233.
Write down 9 as next digit of the result. 
Result so far: 69.0
The remainder is 233 after subtracting 3402 from 3635.
Grab the next digit (5) from the dividend, add it to 233, then carry on: 2335 / 378

Moving on to step 6:
2335 divided by 378 is 6 with a remainder of 67.
The number 6 becomes the next digit in our result. 
Result so far: 696.0
Subtract 2268 from 2335 to get 67.
Include the next digit (7) from the dividend after 67, then repeat: 677 / 378

On to step 7:
When dividing 677 by 378, we get 1 with a remainder of 299.
Use 1 as the next digit of our solution. 
Result so far: 6961.0
The remainder is 299 after subtracting 378 from 677.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Going ahead to step 8:
When dividing 2990 by 378, we get 7 with a remainder of 344.
The next digit of our result is 7. 
Result so far: 6961.7
Deduct 2646 from 2990 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 9:
378 goes into 3440 9 times with a remainder of 38.
The next digit of our result is 9. 
Result so far: 6961.79
Deduct 3402 from 3440 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
378 goes into 380 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 6961.791
Subtracting 378 from 380 leaves us with 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 11:
If we divide 20 by 378, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 6961.791
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
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: 6961.791
If we take 0 away from 200, we end up 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.

The final outcome is 6961.791, with a leftover of 0.0002.
