69340584 ÷ 810 
We want to divide 69340584 by 810.

Going ahead to step 1:
When dividing 6 by 810, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 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.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Include the next digit (3) from the dividend after 69, then repeat: 693 / 810

Let's proceed to step 3:
810 can be fit into 693 0 times, resulting in a remainder of 693.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 693, we end up with 693.
Fetch the next digit (4) from the dividend, attach it to 693 and continue: 6934 / 810

Step 4:
810 goes into 6934 8 times with a remainder of 454.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 6480 from 6934 to get 454.
Append the next digit (0) from the dividend to 454 and continue with: 4540 / 810

Moving on to step 5:
If we divide 4540 by 810, we get 5 and a remainder of 490.
Use 5 as the next digit of our solution. 
Result so far: 85.0
If we take 4050 away from 4540, we end up with 490.
Include the next digit (5) from the dividend after 490, then repeat: 4905 / 810

Step 6:
If we divide 4905 by 810, we get 6 and a remainder of 45.
The number 6 becomes the next digit in our result. 
Result so far: 856.0
Subtract 4860 from 4905 to get 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 810

Let's proceed to step 7:
810 can be fit into 458 0 times, resulting in a remainder of 458.
Write down 0 as next digit of the result. 
Result so far: 8560.0
Subtracting 0 from 458 leaves us with 458.
Take the next digit (4) from the dividend and append it to 458, then repeat: 4584 / 810

On to step 8:
810 can be fit into 4584 5 times, resulting in a remainder of 534.
Put 5 as the next digit of the answer. 
Result so far: 85605.0
Deduct 4050 from 4584 and we're left with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Going ahead to step 9:
When dividing 5340 by 810, we get 6 with a remainder of 480.
Write down 6 as next digit of the result. 
Result so far: 85605.6
Subtract 4860 from 5340 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 10:
4800 divided by 810 is 5 with a remainder of 750.
Use 5 as the next digit of our solution. 
Result so far: 85605.65
The remainder is 750 after subtracting 4050 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Let's proceed to step 11:
If we divide 7500 by 810, we get 9 and a remainder of 210.
Write down 9 as next digit of the result. 
Result so far: 85605.659
The remainder is 210 after subtracting 7290 from 7500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 12:
810 can be fit into 2100 2 times, resulting in a remainder of 480.
Put 2 as the next digit of the answer. 
Result so far: 85605.6592
Subtracting 1620 from 2100 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 13:
When dividing 4800 by 810, we get 5 with a remainder of 750.
Write down 5 as next digit of the result. 
Result so far: 85605.65925
Deduct 4050 from 4800 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 14:
When dividing 7500 by 810, we get 9 with a remainder of 210.
Put 9 as the next digit of the answer. 
Result so far: 85605.659259
If we take 7290 away from 7500, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 15:
When dividing 2100 by 810, we get 2 with a remainder of 480.
The next digit of our result is 2. 
Result so far: 85605.6592592
If we take 1620 away from 2100, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 16:
810 can be fit into 4800 5 times, resulting in a remainder of 750.
Record the quotient 5 as the next digit in the result. 
Result so far: 85605.65925925
Subtract 4050 from 4800 to get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

In conclusion, the division gives 85605.65925925 with a balance of 7.5e-07.
