We look at the division of 69914015 by 810 
Our goal is to divide 69914015 by 810.

Advancing to step 1:
810 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 810

On to step 2:
69 divided by 810 is 0 with a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Bring next digit (9) of the dividend behind the 69 and repeat the process: 699 / 810

Step 3:
When dividing 699 by 810, we get 0 with a remainder of 699.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 699 after subtracting 0 from 699.
Fetch the next digit (1) from the dividend, attach it to 699 and continue: 6991 / 810

Step 4:
If we divide 6991 by 810, we get 8 and a remainder of 511.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 511 after subtracting 6480 from 6991.
Bring next digit (4) of the dividend behind the 511 and repeat the process: 5114 / 810

Let's proceed to step 5:
The number 810 fits into 5114 6 times, leaving a remainder of 254.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Subtract 4860 from 5114 to get 254.
Include the next digit (0) from the dividend after 254, then repeat: 2540 / 810

Advancing to step 6:
If we divide 2540 by 810, we get 3 and a remainder of 110.
Record the quotient 3 as the next digit in the result. 
Result so far: 863.0
Subtract 2430 from 2540 to get 110.
Take the next digit (1) from the dividend and append it to 110, then repeat: 1101 / 810

Let's proceed to step 7:
When dividing 1101 by 810, we get 1 with a remainder of 291.
Write down 1 as next digit of the result. 
Result so far: 8631.0
The remainder is 291 after subtracting 810 from 1101.
Take the next digit (5) from the dividend and append it to 291, then repeat: 2915 / 810

Step 8:
When dividing 2915 by 810, we get 3 with a remainder of 485.
The next digit of our result is 3. 
Result so far: 86313.0
If we subtract 2430 from 2915, we get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Moving on to step 9:
4850 divided by 810 is 5 with a remainder of 800.
Use 5 as the next digit of our solution. 
Result so far: 86313.5
Deduct 4050 from 4850 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 10:
If we divide 8000 by 810, we get 9 and a remainder of 710.
Use 9 as the next digit of our solution. 
Result so far: 86313.59
If we take 7290 away from 8000, we end up with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Step 11:
If we divide 7100 by 810, we get 8 and a remainder of 620.
Put 8 as the next digit of the answer. 
Result so far: 86313.598
If we subtract 6480 from 7100, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 12:
810 goes into 6200 7 times with a remainder of 530.
Put 7 as the next digit of the answer. 
Result so far: 86313.5987
If we take 5670 away from 6200, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Moving on to step 13:
If we divide 5300 by 810, we get 6 and a remainder of 440.
Record the quotient 6 as the next digit in the result. 
Result so far: 86313.59876
If we take 4860 away from 5300, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 14:
4400 divided by 810 is 5 with a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 86313.598765
Subtracting 4050 from 4400 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 15:
When dividing 3500 by 810, we get 4 with a remainder of 260.
The number 4 becomes the next digit in our result. 
Result so far: 86313.5987654
The remainder is 260 after subtracting 3240 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 16:
2600 divided by 810 is 3 with a remainder of 170.
The next digit of our result is 3. 
Result so far: 86313.59876543
The remainder is 170 after subtracting 2430 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

In conclusion, the division gives 86313.59876543 with a balance of 1.7e-07.
