We divide 21670052 by 810
We're looking to find how many times 810 goes into 21670052.

On to step 1:
2 divided by 810 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 810

Moving on to step 2:
810 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 810

Advancing to step 3:
When dividing 216 by 810, we get 0 with a remainder of 216.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 216 leaves us with 216.
Bring next digit (7) of the dividend behind the 216 and repeat the process: 2167 / 810

Step 4:
The number 810 fits into 2167 2 times, leaving a remainder of 547.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1620 from 2167, we get 547.
Include the next digit (0) from the dividend after 547, then repeat: 5470 / 810

Let's proceed to step 5:
810 can be fit into 5470 6 times, resulting in a remainder of 610.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Subtract 4860 from 5470 to get 610.
Append the next digit (0) from the dividend to 610 and continue with: 6100 / 810

On to step 6:
If we divide 6100 by 810, we get 7 and a remainder of 430.
Record the quotient 7 as the next digit in the result. 
Result so far: 267.0
If we take 5670 away from 6100, we end up with 430.
Grab the next digit (5) from the dividend, add it to 430, then carry on: 4305 / 810

Moving on to step 7:
4305 divided by 810 is 5 with a remainder of 255.
Record the quotient 5 as the next digit in the result. 
Result so far: 2675.0
The remainder is 255 after subtracting 4050 from 4305.
Fetch the next digit (2) from the dividend, attach it to 255 and continue: 2552 / 810

Moving on to step 8:
If we divide 2552 by 810, we get 3 and a remainder of 122.
Put 3 as the next digit of the answer. 
Result so far: 26753.0
If we take 2430 away from 2552, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 9:
810 can be fit into 1220 1 times, resulting in a remainder of 410.
The next digit of our result is 1. 
Result so far: 26753.1
Subtracting 810 from 1220 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 10:
810 can be fit into 4100 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 26753.15
The remainder is 50 after subtracting 4050 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
810 goes into 500 0 times with a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 26753.15
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 12:
If we divide 5000 by 810, we get 6 and a remainder of 140.
Write down 6 as next digit of the result. 
Result so far: 26753.1506
The remainder is 140 after subtracting 4860 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 13:
When dividing 1400 by 810, we get 1 with a remainder of 590.
The number 1 becomes the next digit in our result. 
Result so far: 26753.15061
Subtract 810 from 1400 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Let's proceed to step 14:
When dividing 5900 by 810, we get 7 with a remainder of 230.
The number 7 becomes the next digit in our result. 
Result so far: 26753.150617
Subtract 5670 from 5900 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 15:
If we divide 2300 by 810, we get 2 and a remainder of 680.
Put 2 as the next digit of the answer. 
Result so far: 26753.1506172
Subtract 1620 from 2300 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Moving on to step 16:
The number 810 fits into 6800 8 times, leaving a remainder of 320.
Put 8 as the next digit of the answer. 
Result so far: 26753.15061728
If we subtract 6480 from 6800, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

In conclusion, the division gives 26753.15061728 with a balance of 3.2e-07.
