Let's divide 2651026 by 399
Our goal is to divide 2651026 by 399.

Advancing to step 1:
The number 399 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 399

Going ahead to step 2:
The number 399 fits into 26 0 times, leaving a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 399

Moving on to step 3:
399 goes into 265 0 times with a remainder of 265.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 265 leaves us with 265.
Append the next digit (1) from the dividend to 265 and continue with: 2651 / 399

On to step 4:
2651 divided by 399 is 6 with a remainder of 257.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 2394 from 2651 leaves us with 257.
Grab the next digit (0) from the dividend, add it to 257, then carry on: 2570 / 399

Let's proceed to step 5:
399 goes into 2570 6 times with a remainder of 176.
The next digit of our result is 6. 
Result so far: 66.0
The remainder is 176 after subtracting 2394 from 2570.
Bring next digit (2) of the dividend behind the 176 and repeat the process: 1762 / 399

Step 6:
When dividing 1762 by 399, we get 4 with a remainder of 166.
Use 4 as the next digit of our solution. 
Result so far: 664.0
The remainder is 166 after subtracting 1596 from 1762.
Append the next digit (6) from the dividend to 166 and continue with: 1666 / 399

Going ahead to step 7:
1666 divided by 399 is 4 with a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 6644.0
Deduct 1596 from 1666 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
399 goes into 700 1 times with a remainder of 301.
Use 1 as the next digit of our solution. 
Result so far: 6644.1
Subtracting 399 from 700 leaves us with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Step 9:
The number 399 fits into 3010 7 times, leaving a remainder of 217.
Use 7 as the next digit of our solution. 
Result so far: 6644.17
Subtract 2793 from 3010 to get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

On to step 10:
399 can be fit into 2170 5 times, resulting in a remainder of 175.
The next digit of our result is 5. 
Result so far: 6644.175
If we take 1995 away from 2170, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 11:
1750 divided by 399 is 4 with a remainder of 154.
Use 4 as the next digit of our solution. 
Result so far: 6644.1754
Subtract 1596 from 1750 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 12:
399 goes into 1540 3 times with a remainder of 343.
The next digit of our result is 3. 
Result so far: 6644.17543
If we subtract 1197 from 1540, we get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Advancing to step 13:
The number 399 fits into 3430 8 times, leaving a remainder of 238.
Record the quotient 8 as the next digit in the result. 
Result so far: 6644.175438
Subtracting 3192 from 3430 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 14:
399 can be fit into 2380 5 times, resulting in a remainder of 385.
The next digit of our result is 5. 
Result so far: 6644.1754385
If we take 1995 away from 2380, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Let's proceed to step 15:
When dividing 3850 by 399, we get 9 with a remainder of 259.
Put 9 as the next digit of the answer. 
Result so far: 6644.17543859
The remainder is 259 after subtracting 3591 from 3850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

In conclusion, the division gives 6644.17543859 with a balance of 2.59e-07.
