73961698 divided by 816 
We want to divide 73961698 by 816.

Step 1:
When dividing 7 by 816, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 816

Let's proceed to step 2:
The number 816 fits into 73 0 times, leaving a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Take the next digit (9) from the dividend and append it to 73, then repeat: 739 / 816

Let's proceed to step 3:
The number 816 fits into 739 0 times, leaving a remainder of 739.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 739, we end up with 739.
Bring next digit (6) of the dividend behind the 739 and repeat the process: 7396 / 816

Moving on to step 4:
816 can be fit into 7396 9 times, resulting in a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 7344 from 7396 to get 52.
Grab the next digit (1) from the dividend, add it to 52, then carry on: 521 / 816

Advancing to step 5:
When dividing 521 by 816, we get 0 with a remainder of 521.
Write down 0 as next digit of the result. 
Result so far: 90.0
Deduct 0 from 521 and we're left with 521.
Bring next digit (6) of the dividend behind the 521 and repeat the process: 5216 / 816

On to step 6:
When dividing 5216 by 816, we get 6 with a remainder of 320.
The next digit of our result is 6. 
Result so far: 906.0
If we subtract 4896 from 5216, we get 320.
Include the next digit (9) from the dividend after 320, then repeat: 3209 / 816

Step 7:
3209 divided by 816 is 3 with a remainder of 761.
Use 3 as the next digit of our solution. 
Result so far: 9063.0
Subtracting 2448 from 3209 leaves us with 761.
Fetch the next digit (8) from the dividend, attach it to 761 and continue: 7618 / 816

Step 8:
816 goes into 7618 9 times with a remainder of 274.
The number 9 becomes the next digit in our result. 
Result so far: 90639.0
If we subtract 7344 from 7618, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 9:
The number 816 fits into 2740 3 times, leaving a remainder of 292.
Use 3 as the next digit of our solution. 
Result so far: 90639.3
Subtracting 2448 from 2740 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 10:
2920 divided by 816 is 3 with a remainder of 472.
Put 3 as the next digit of the answer. 
Result so far: 90639.33
Subtract 2448 from 2920 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

After the division, we end up with 90639.33 and a remainder of 0.472.
