70689122 ÷ 816 
Let's see how many times 816 fits into 70689122.

Advancing to step 1:
7 divided by 816 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 816

Let's proceed to step 2:
70 divided by 816 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Append the next digit (6) from the dividend to 70 and continue with: 706 / 816

Moving on to step 3:
706 divided by 816 is 0 with a remainder of 706.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 706, we end up with 706.
Fetch the next digit (8) from the dividend, attach it to 706 and continue: 7068 / 816

On to step 4:
If we divide 7068 by 816, we get 8 and a remainder of 540.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 6528 from 7068 leaves us with 540.
Append the next digit (9) from the dividend to 540 and continue with: 5409 / 816

Step 5:
When dividing 5409 by 816, we get 6 with a remainder of 513.
Put 6 as the next digit of the answer. 
Result so far: 86.0
The remainder is 513 after subtracting 4896 from 5409.
Fetch the next digit (1) from the dividend, attach it to 513 and continue: 5131 / 816

On to step 6:
The number 816 fits into 5131 6 times, leaving a remainder of 235.
Write down 6 as next digit of the result. 
Result so far: 866.0
Deduct 4896 from 5131 and we're left with 235.
Include the next digit (2) from the dividend after 235, then repeat: 2352 / 816

Going ahead to step 7:
If we divide 2352 by 816, we get 2 and a remainder of 720.
Write down 2 as next digit of the result. 
Result so far: 8662.0
Subtract 1632 from 2352 to get 720.
Take the next digit (2) from the dividend and append it to 720, then repeat: 7202 / 816

Step 8:
If we divide 7202 by 816, we get 8 and a remainder of 674.
Write down 8 as next digit of the result. 
Result so far: 86628.0
The remainder is 674 after subtracting 6528 from 7202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Going ahead to step 9:
The number 816 fits into 6740 8 times, leaving a remainder of 212.
Write down 8 as next digit of the result. 
Result so far: 86628.8
If we subtract 6528 from 6740, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 10:
The number 816 fits into 2120 2 times, leaving a remainder of 488.
The number 2 becomes the next digit in our result. 
Result so far: 86628.82
Subtracting 1632 from 2120 leaves us with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Step 11:
816 can be fit into 4880 5 times, resulting in a remainder of 800.
Use 5 as the next digit of our solution. 
Result so far: 86628.825
The remainder is 800 after subtracting 4080 from 4880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Moving on to step 12:
816 goes into 8000 9 times with a remainder of 656.
Use 9 as the next digit of our solution. 
Result so far: 86628.8259
If we subtract 7344 from 8000, we get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Going ahead to step 13:
6560 divided by 816 is 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 86628.82598
Deduct 6528 from 6560 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
If we divide 320 by 816, we get 0 and a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 86628.82598
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 15:
3200 divided by 816 is 3 with a remainder of 752.
Use 3 as the next digit of our solution. 
Result so far: 86628.8259803
Subtracting 2448 from 3200 leaves us with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

On to step 16:
The number 816 fits into 7520 9 times, leaving a remainder of 176.
Write down 9 as next digit of the result. 
Result so far: 86628.82598039
The remainder is 176 after subtracting 7344 from 7520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

After the division, we end up with 86628.82598039 and a remainder of 1.76e-07.
