Let's divide 13896830 by 661
We want to divide 13896830 by 661.

Let's proceed to step 1:
1 divided by 661 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 661

Going ahead to step 2:
661 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 661

Moving on to step 3:
When dividing 138 by 661, we get 0 with a remainder of 138.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 138 and we're left with 138.
Fetch the next digit (9) from the dividend, attach it to 138 and continue: 1389 / 661

Advancing to step 4:
When dividing 1389 by 661, we get 2 with a remainder of 67.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 67 after subtracting 1322 from 1389.
Bring next digit (6) of the dividend behind the 67 and repeat the process: 676 / 661

Going ahead to step 5:
661 goes into 676 1 times with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 661 from 676 and we're left with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 661

On to step 6:
661 goes into 158 0 times with a remainder of 158.
Use 0 as the next digit of our solution. 
Result so far: 210.0
The remainder is 158 after subtracting 0 from 158.
Append the next digit (3) from the dividend to 158 and continue with: 1583 / 661

Step 7:
When dividing 1583 by 661, we get 2 with a remainder of 261.
Put 2 as the next digit of the answer. 
Result so far: 2102.0
Subtract 1322 from 1583 to get 261.
Fetch the next digit (0) from the dividend, attach it to 261 and continue: 2610 / 661

Step 8:
The number 661 fits into 2610 3 times, leaving a remainder of 627.
The number 3 becomes the next digit in our result. 
Result so far: 21023.0
Subtract 1983 from 2610 to get 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Moving on to step 9:
The number 661 fits into 6270 9 times, leaving a remainder of 321.
The next digit of our result is 9. 
Result so far: 21023.9
Deduct 5949 from 6270 and we're left with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

On to step 10:
When dividing 3210 by 661, we get 4 with a remainder of 566.
Write down 4 as next digit of the result. 
Result so far: 21023.94
Deduct 2644 from 3210 and we're left with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Going ahead to step 11:
661 goes into 5660 8 times with a remainder of 372.
The next digit of our result is 8. 
Result so far: 21023.948
The remainder is 372 after subtracting 5288 from 5660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 12:
When dividing 3720 by 661, we get 5 with a remainder of 415.
Use 5 as the next digit of our solution. 
Result so far: 21023.9485
If we take 3305 away from 3720, we end up with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

On to step 13:
661 goes into 4150 6 times with a remainder of 184.
Put 6 as the next digit of the answer. 
Result so far: 21023.94856
Subtract 3966 from 4150 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 14:
When dividing 1840 by 661, we get 2 with a remainder of 518.
The next digit of our result is 2. 
Result so far: 21023.948562
Subtracting 1322 from 1840 leaves us with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Going ahead to step 15:
The number 661 fits into 5180 7 times, leaving a remainder of 553.
Put 7 as the next digit of the answer. 
Result so far: 21023.9485627
The remainder is 553 after subtracting 4627 from 5180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Moving on to step 16:
661 goes into 5530 8 times with a remainder of 242.
Use 8 as the next digit of our solution. 
Result so far: 21023.94856278
Subtracting 5288 from 5530 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

The final result is 21023.94856278 with a remainder of 2.42e-07.
