26379660 divided by 398 
Our goal is to divide 26379660 by 398.

Step 1:
If we divide 2 by 398, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 398

Advancing to step 2:
398 can be fit into 26 0 times, resulting in a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 398

On to step 3:
398 goes into 263 0 times with a remainder of 263.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 263 leaves us with 263.
Bring next digit (7) of the dividend behind the 263 and repeat the process: 2637 / 398

Let's proceed to step 4:
398 goes into 2637 6 times with a remainder of 249.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 2388 from 2637 to get 249.
Take the next digit (9) from the dividend and append it to 249, then repeat: 2499 / 398

Step 5:
398 goes into 2499 6 times with a remainder of 111.
The next digit of our result is 6. 
Result so far: 66.0
Subtracting 2388 from 2499 leaves us with 111.
Include the next digit (6) from the dividend after 111, then repeat: 1116 / 398

Moving on to step 6:
398 can be fit into 1116 2 times, resulting in a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 662.0
Deduct 796 from 1116 and we're left with 320.
Bring next digit (6) of the dividend behind the 320 and repeat the process: 3206 / 398

Let's proceed to step 7:
When dividing 3206 by 398, we get 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 6628.0
Deduct 3184 from 3206 and we're left with 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 398

Step 8:
220 divided by 398 is 0 with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 66280.0
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 9:
2200 divided by 398 is 5 with a remainder of 210.
Use 5 as the next digit of our solution. 
Result so far: 66280.5
If we subtract 1990 from 2200, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 10:
398 can be fit into 2100 5 times, resulting in a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 66280.55
Subtract 1990 from 2100 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

In conclusion, the division gives 66280.55 with a balance of 0.11.
