26838280 ÷ 661 
We want to divide 26838280 by 661.

Step 1:
When dividing 2 by 661, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 661

Step 2:
When dividing 26 by 661, we get 0 with a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 661

Going ahead to step 3:
661 goes into 268 0 times with a remainder of 268.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 268, we get 268.
Append the next digit (3) from the dividend to 268 and continue with: 2683 / 661

Let's proceed to step 4:
When dividing 2683 by 661, we get 4 with a remainder of 39.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 2644 away from 2683, we end up with 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 661

Advancing to step 5:
661 goes into 398 0 times with a remainder of 398.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we subtract 0 from 398, we get 398.
Grab the next digit (2) from the dividend, add it to 398, then carry on: 3982 / 661

On to step 6:
661 can be fit into 3982 6 times, resulting in a remainder of 16.
The next digit of our result is 6. 
Result so far: 406.0
The remainder is 16 after subtracting 3966 from 3982.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 661

On to step 7:
661 can be fit into 168 0 times, resulting in a remainder of 168.
Write down 0 as next digit of the result. 
Result so far: 4060.0
Subtract 0 from 168 to get 168.
Append the next digit (0) from the dividend to 168 and continue with: 1680 / 661

Advancing to step 8:
If we divide 1680 by 661, we get 2 and a remainder of 358.
Record the quotient 2 as the next digit in the result. 
Result so far: 40602.0
Subtracting 1322 from 1680 leaves us with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Step 9:
661 can be fit into 3580 5 times, resulting in a remainder of 275.
Use 5 as the next digit of our solution. 
Result so far: 40602.5
If we take 3305 away from 3580, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 10:
2750 divided by 661 is 4 with a remainder of 106.
Use 4 as the next digit of our solution. 
Result so far: 40602.54
Subtracting 2644 from 2750 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 11:
661 goes into 1060 1 times with a remainder of 399.
Use 1 as the next digit of our solution. 
Result so far: 40602.541
Deduct 661 from 1060 and we're left with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Going ahead to step 12:
3990 divided by 661 is 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 40602.5416
If we take 3966 away from 3990, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
240 divided by 661 is 0 with a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 40602.5416
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 14:
The number 661 fits into 2400 3 times, leaving a remainder of 417.
Put 3 as the next digit of the answer. 
Result so far: 40602.541603
Subtract 1983 from 2400 to get 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Let's proceed to step 15:
If we divide 4170 by 661, we get 6 and a remainder of 204.
The next digit of our result is 6. 
Result so far: 40602.5416036
If we take 3966 away from 4170, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 16:
The number 661 fits into 2040 3 times, leaving a remainder of 57.
The next digit of our result is 3. 
Result so far: 40602.54160363
Subtract 1983 from 2040 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

In conclusion, the division gives 40602.54160363 with a balance of 5.7e-08.
