We're dividing 51623929 by 65 
We want to figure out the number of times 51623929 can be divided by 65.

Let's proceed to step 1:
65 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 65

Moving on to step 2:
65 goes into 51 0 times with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Grab the next digit (6) from the dividend, add it to 51, then carry on: 516 / 65

Advancing to step 3:
65 goes into 516 7 times with a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 455 from 516 leaves us with 61.
Grab the next digit (2) from the dividend, add it to 61, then carry on: 612 / 65

Moving on to step 4:
612 divided by 65 is 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 79.0
The remainder is 27 after subtracting 585 from 612.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 65

Moving on to step 5:
65 can be fit into 273 4 times, resulting in a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 794.0
Deduct 260 from 273 and we're left with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 65

Moving on to step 6:
65 goes into 139 2 times with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 7942.0
If we subtract 130 from 139, we get 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 65

Let's proceed to step 7:
The number 65 fits into 92 1 times, leaving a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 79421.0
Subtracting 65 from 92 leaves us with 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 65

Going ahead to step 8:
When dividing 279 by 65, we get 4 with a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 794214.0
Subtract 260 from 279 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
If we divide 190 by 65, we get 2 and a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 794214.2
Subtracting 130 from 190 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
65 goes into 600 9 times with a remainder of 15.
The next digit of our result is 9. 
Result so far: 794214.29
If we take 585 away from 600, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
65 goes into 150 2 times with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 794214.292
Deduct 130 from 150 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
When dividing 200 by 65, we get 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 794214.2923
Subtract 195 from 200 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
When dividing 50 by 65, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 794214.2923
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
When dividing 500 by 65, we get 7 with a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 794214.292307
If we take 455 away from 500, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 15:
450 divided by 65 is 6 with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 794214.2923076
If we take 390 away from 450, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 16:
65 goes into 600 9 times with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 794214.29230769
Deduct 585 from 600 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 794214.29230769, with a leftover of 1.5e-08.
