26624821 ÷ 378 
Our goal is to divide 26624821 by 378.

Let's proceed to step 1:
When dividing 2 by 378, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 378

On to step 2:
26 divided by 378 is 0 with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Include the next digit (6) from the dividend after 26, then repeat: 266 / 378

On to step 3:
378 goes into 266 0 times with a remainder of 266.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 266, we get 266.
Append the next digit (2) from the dividend to 266 and continue with: 2662 / 378

Going ahead to step 4:
The number 378 fits into 2662 7 times, leaving a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 2646 from 2662 and we're left with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 378

Going ahead to step 5:
When dividing 164 by 378, we get 0 with a remainder of 164.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
If we take 0 away from 164, we end up with 164.
Include the next digit (8) from the dividend after 164, then repeat: 1648 / 378

Advancing to step 6:
The number 378 fits into 1648 4 times, leaving a remainder of 136.
The next digit of our result is 4. 
Result so far: 704.0
The remainder is 136 after subtracting 1512 from 1648.
Include the next digit (2) from the dividend after 136, then repeat: 1362 / 378

On to step 7:
The number 378 fits into 1362 3 times, leaving a remainder of 228.
Put 3 as the next digit of the answer. 
Result so far: 7043.0
If we subtract 1134 from 1362, we get 228.
Include the next digit (1) from the dividend after 228, then repeat: 2281 / 378

Moving on to step 8:
The number 378 fits into 2281 6 times, leaving a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 70436.0
Subtracting 2268 from 2281 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
When dividing 130 by 378, we get 0 with a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 70436.0
If we subtract 0 from 130, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 10:
If we divide 1300 by 378, we get 3 and a remainder of 166.
Write down 3 as next digit of the result. 
Result so far: 70436.03
Deduct 1134 from 1300 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 11:
378 can be fit into 1660 4 times, resulting in a remainder of 148.
Record the quotient 4 as the next digit in the result. 
Result so far: 70436.034
If we subtract 1512 from 1660, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 12:
The number 378 fits into 1480 3 times, leaving a remainder of 346.
Write down 3 as next digit of the result. 
Result so far: 70436.0343
Subtracting 1134 from 1480 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 13:
When dividing 3460 by 378, we get 9 with a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 70436.03439
If we subtract 3402 from 3460, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 14:
378 goes into 580 1 times with a remainder of 202.
Record the quotient 1 as the next digit in the result. 
Result so far: 70436.034391
Deduct 378 from 580 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 15:
If we divide 2020 by 378, we get 5 and a remainder of 130.
The number 5 becomes the next digit in our result. 
Result so far: 70436.0343915
Subtract 1890 from 2020 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 16:
1300 divided by 378 is 3 with a remainder of 166.
The number 3 becomes the next digit in our result. 
Result so far: 70436.03439153
If we subtract 1134 from 1300, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

After the division, we end up with 70436.03439153 and a remainder of 1.66e-07.
