Let's divide 51395993 by 65
We want to figure out the number of times 51395993 can be divided by 65.

Step 1:
65 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 65

Advancing to step 2:
51 divided by 65 is 0 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.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 65

Moving on to step 3:
513 divided by 65 is 7 with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 455 from 513 and we're left with 58.
Fetch the next digit (9) from the dividend, attach it to 58 and continue: 589 / 65

Step 4:
65 goes into 589 9 times with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Deduct 585 from 589 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 65

Going ahead to step 5:
65 goes into 45 0 times with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 790.0
Subtract 0 from 45 to get 45.
Include the next digit (9) from the dividend after 45, then repeat: 459 / 65

Moving on to step 6:
When dividing 459 by 65, we get 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 7907.0
If we take 455 away from 459, we end up with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 65

On to step 7:
49 divided by 65 is 0 with a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 79070.0
The remainder is 49 after subtracting 0 from 49.
Grab the next digit (3) from the dividend, add it to 49, then carry on: 493 / 65

Moving on to step 8:
If we divide 493 by 65, we get 7 and a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 790707.0
The remainder is 38 after subtracting 455 from 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
380 divided by 65 is 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 790707.5
Subtract 325 from 380 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
65 goes into 550 8 times with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 790707.58
If we take 520 away from 550, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
When dividing 300 by 65, we get 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 790707.584
If we subtract 260 from 300, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
If we divide 400 by 65, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 790707.5846
If we take 390 away from 400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
When dividing 100 by 65, we get 1 with a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 790707.58461
The remainder is 35 after subtracting 65 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 14:
65 can be fit into 350 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 790707.584615
If we subtract 325 from 350, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 15:
When dividing 250 by 65, we get 3 with a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 790707.5846153
If we take 195 away from 250, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 16:
When dividing 550 by 65, we get 8 with a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 790707.58461538
The remainder is 30 after subtracting 520 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 790707.58461538 and a remainder of 3e-08.
