We divide 19785490 by 810
We're looking to find how many times 810 goes into 19785490.

Moving on to step 1:
When dividing 1 by 810, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 810

On to step 2:
810 goes into 19 0 times with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 810

Step 3:
197 divided by 810 is 0 with a remainder of 197.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 197 and we're left with 197.
Append the next digit (8) from the dividend to 197 and continue with: 1978 / 810

On to step 4:
When dividing 1978 by 810, we get 2 with a remainder of 358.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1620 from 1978 to get 358.
Take the next digit (5) from the dividend and append it to 358, then repeat: 3585 / 810

Advancing to step 5:
810 goes into 3585 4 times with a remainder of 345.
The next digit of our result is 4. 
Result so far: 24.0
Subtracting 3240 from 3585 leaves us with 345.
Append the next digit (4) from the dividend to 345 and continue with: 3454 / 810

Step 6:
3454 divided by 810 is 4 with a remainder of 214.
Put 4 as the next digit of the answer. 
Result so far: 244.0
Subtract 3240 from 3454 to get 214.
Append the next digit (9) from the dividend to 214 and continue with: 2149 / 810

On to step 7:
The number 810 fits into 2149 2 times, leaving a remainder of 529.
Record the quotient 2 as the next digit in the result. 
Result so far: 2442.0
The remainder is 529 after subtracting 1620 from 2149.
Bring next digit (0) of the dividend behind the 529 and repeat the process: 5290 / 810

Going ahead to step 8:
The number 810 fits into 5290 6 times, leaving a remainder of 430.
Write down 6 as next digit of the result. 
Result so far: 24426.0
Deduct 4860 from 5290 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 9:
The number 810 fits into 4300 5 times, leaving a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 24426.5
The remainder is 250 after subtracting 4050 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 10:
810 goes into 2500 3 times with a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 24426.53
Subtract 2430 from 2500 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 11:
The number 810 fits into 700 0 times, leaving a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 24426.53
If we take 0 away from 700, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 12:
The number 810 fits into 7000 8 times, leaving a remainder of 520.
Write down 8 as next digit of the result. 
Result so far: 24426.5308
Deduct 6480 from 7000 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 13:
810 goes into 5200 6 times with a remainder of 340.
Put 6 as the next digit of the answer. 
Result so far: 24426.53086
If we subtract 4860 from 5200, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 14:
If we divide 3400 by 810, we get 4 and a remainder of 160.
Write down 4 as next digit of the result. 
Result so far: 24426.530864
Deduct 3240 from 3400 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.

Step 15:
810 goes into 1600 1 times with a remainder of 790.
Record the quotient 1 as the next digit in the result. 
Result so far: 24426.5308641
Deduct 810 from 1600 and we're left with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Step 16:
810 goes into 7900 9 times with a remainder of 610.
The number 9 becomes the next digit in our result. 
Result so far: 24426.53086419
Deduct 7290 from 7900 and we're left with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

In conclusion, the division gives 24426.53086419 with a balance of 6.1e-07.
