Let's divide 65997646 by 813
We want to figure out the number of times 65997646 can be divided by 813.

Moving on to step 1:
If we divide 6 by 813, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 813

Going ahead to step 2:
813 can be fit into 65 0 times, resulting in a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Bring next digit (9) of the dividend behind the 65 and repeat the process: 659 / 813

Let's proceed to step 3:
When dividing 659 by 813, we get 0 with a remainder of 659.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 659 to get 659.
Bring next digit (9) of the dividend behind the 659 and repeat the process: 6599 / 813

Going ahead to step 4:
The number 813 fits into 6599 8 times, leaving a remainder of 95.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 6504 from 6599 and we're left with 95.
Take the next digit (7) from the dividend and append it to 95, then repeat: 957 / 813

Advancing to step 5:
If we divide 957 by 813, we get 1 and a remainder of 144.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we take 813 away from 957, we end up with 144.
Append the next digit (6) from the dividend to 144 and continue with: 1446 / 813

Moving on to step 6:
When dividing 1446 by 813, we get 1 with a remainder of 633.
The next digit of our result is 1. 
Result so far: 811.0
Subtract 813 from 1446 to get 633.
Append the next digit (4) from the dividend to 633 and continue with: 6334 / 813

Step 7:
If we divide 6334 by 813, we get 7 and a remainder of 643.
The number 7 becomes the next digit in our result. 
Result so far: 8117.0
If we subtract 5691 from 6334, we get 643.
Bring next digit (6) of the dividend behind the 643 and repeat the process: 6436 / 813

Advancing to step 8:
6436 divided by 813 is 7 with a remainder of 745.
Put 7 as the next digit of the answer. 
Result so far: 81177.0
Deduct 5691 from 6436 and we're left with 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Step 9:
7450 divided by 813 is 9 with a remainder of 133.
Write down 9 as next digit of the result. 
Result so far: 81177.9
Subtract 7317 from 7450 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 10:
The number 813 fits into 1330 1 times, leaving a remainder of 517.
The next digit of our result is 1. 
Result so far: 81177.91
Subtract 813 from 1330 to get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Step 11:
If we divide 5170 by 813, we get 6 and a remainder of 292.
Put 6 as the next digit of the answer. 
Result so far: 81177.916
If we take 4878 away from 5170, we end up 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.

On to step 12:
If we divide 2920 by 813, we get 3 and a remainder of 481.
Write down 3 as next digit of the result. 
Result so far: 81177.9163
Subtract 2439 from 2920 to get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Moving on to step 13:
If we divide 4810 by 813, we get 5 and a remainder of 745.
Use 5 as the next digit of our solution. 
Result so far: 81177.91635
If we take 4065 away from 4810, we end up with 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Moving on to step 14:
The number 813 fits into 7450 9 times, leaving a remainder of 133.
The next digit of our result is 9. 
Result so far: 81177.916359
If we subtract 7317 from 7450, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 15:
When dividing 1330 by 813, we get 1 with a remainder of 517.
Write down 1 as next digit of the result. 
Result so far: 81177.9163591
Subtracting 813 from 1330 leaves us with 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Advancing to step 16:
If we divide 5170 by 813, we get 6 and a remainder of 292.
The number 6 becomes the next digit in our result. 
Result so far: 81177.91635916
Deduct 4878 from 5170 and we're left 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.

The final result is 81177.91635916 with a remainder of 2.92e-07.
