12805504 divided by 210 
We want to figure out the number of times 12805504 can be divided by 210.

Step 1:
The number 210 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 210

Moving on to step 2:
210 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 210

Step 3:
When dividing 128 by 210, we get 0 with a remainder of 128.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 128 and we're left with 128.
Take the next digit (0) from the dividend and append it to 128, then repeat: 1280 / 210

Advancing to step 4:
When dividing 1280 by 210, we get 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 1260 away from 1280, we end up with 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 210

On to step 5:
If we divide 205 by 210, we get 0 and a remainder of 205.
Write down 0 as next digit of the result. 
Result so far: 60.0
Subtract 0 from 205 to get 205.
Fetch the next digit (5) from the dividend, attach it to 205 and continue: 2055 / 210

On to step 6:
If we divide 2055 by 210, we get 9 and a remainder of 165.
The number 9 becomes the next digit in our result. 
Result so far: 609.0
If we subtract 1890 from 2055, we get 165.
Append the next digit (0) from the dividend to 165 and continue with: 1650 / 210

On to step 7:
1650 divided by 210 is 7 with a remainder of 180.
The number 7 becomes the next digit in our result. 
Result so far: 6097.0
The remainder is 180 after subtracting 1470 from 1650.
Bring next digit (4) of the dividend behind the 180 and repeat the process: 1804 / 210

Advancing to step 8:
If we divide 1804 by 210, we get 8 and a remainder of 124.
The number 8 becomes the next digit in our result. 
Result so far: 60978.0
If we subtract 1680 from 1804, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 9:
The number 210 fits into 1240 5 times, leaving a remainder of 190.
Put 5 as the next digit of the answer. 
Result so far: 60978.5
Deduct 1050 from 1240 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 10:
210 can be fit into 1900 9 times, resulting in a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 60978.59
Deduct 1890 from 1900 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
The number 210 fits into 100 0 times, leaving a remainder of 100.
The next digit of our result is 0. 
Result so far: 60978.59
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 12:
The number 210 fits into 1000 4 times, leaving a remainder of 160.
Use 4 as the next digit of our solution. 
Result so far: 60978.5904
Deduct 840 from 1000 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 13:
1600 divided by 210 is 7 with a remainder of 130.
The next digit of our result is 7. 
Result so far: 60978.59047
The remainder is 130 after subtracting 1470 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 14:
The number 210 fits into 1300 6 times, leaving a remainder of 40.
The next digit of our result is 6. 
Result so far: 60978.590476
If we take 1260 away from 1300, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 15:
The number 210 fits into 400 1 times, leaving a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 60978.5904761
Deduct 210 from 400 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 16:
1900 divided by 210 is 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 60978.59047619
If we subtract 1890 from 1900, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 60978.59047619 with a remainder of 1e-08.
