We're dividing 26643737 by 210 
We want to divide 26643737 by 210.

Going ahead to step 1:
210 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
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 / 210

On to step 2:
210 goes into 26 0 times with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 210

Step 3:
If we divide 266 by 210, we get 1 and a remainder of 56.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 210 from 266 and we're left with 56.
Take the next digit (4) from the dividend and append it to 56, then repeat: 564 / 210

Let's proceed to step 4:
If we divide 564 by 210, we get 2 and a remainder of 144.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 420 from 564, we get 144.
Fetch the next digit (3) from the dividend, attach it to 144 and continue: 1443 / 210

On to step 5:
210 can be fit into 1443 6 times, resulting in a remainder of 183.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
Subtracting 1260 from 1443 leaves us with 183.
Append the next digit (7) from the dividend to 183 and continue with: 1837 / 210

Moving on to step 6:
210 goes into 1837 8 times with a remainder of 157.
Record the quotient 8 as the next digit in the result. 
Result so far: 1268.0
If we subtract 1680 from 1837, we get 157.
Fetch the next digit (3) from the dividend, attach it to 157 and continue: 1573 / 210

On to step 7:
If we divide 1573 by 210, we get 7 and a remainder of 103.
The next digit of our result is 7. 
Result so far: 12687.0
Deduct 1470 from 1573 and we're left with 103.
Fetch the next digit (7) from the dividend, attach it to 103 and continue: 1037 / 210

On to step 8:
The number 210 fits into 1037 4 times, leaving a remainder of 197.
The number 4 becomes the next digit in our result. 
Result so far: 126874.0
Subtracting 840 from 1037 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

On to step 9:
If we divide 1970 by 210, we get 9 and a remainder of 80.
Put 9 as the next digit of the answer. 
Result so far: 126874.9
Subtract 1890 from 1970 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
The number 210 fits into 800 3 times, leaving a remainder of 170.
Use 3 as the next digit of our solution. 
Result so far: 126874.93
The remainder is 170 after subtracting 630 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 11:
210 goes into 1700 8 times with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 126874.938
If we take 1680 away from 1700, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
210 can be fit into 200 0 times, resulting in a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 126874.938
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 13:
210 goes into 2000 9 times with a remainder of 110.
Write down 9 as next digit of the result. 
Result so far: 126874.93809
Subtracting 1890 from 2000 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 14:
If we divide 1100 by 210, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 126874.938095
Subtracting 1050 from 1100 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 15:
210 can be fit into 500 2 times, resulting in a remainder of 80.
The next digit of our result is 2. 
Result so far: 126874.9380952
If we subtract 420 from 500, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 16:
The number 210 fits into 800 3 times, leaving a remainder of 170.
Use 3 as the next digit of our solution. 
Result so far: 126874.93809523
Subtracting 630 from 800 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

After the division, we end up with 126874.93809523 and a remainder of 1.7e-07.
