We look at the division of 163621 by 65 
We want to divide 163621 by 65.

On to step 1:
The number 65 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 65

On to step 2:
The number 65 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 65

Moving on to step 3:
65 goes into 163 2 times with a remainder of 33.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 130 from 163 and we're left with 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 65

Let's proceed to step 4:
65 can be fit into 336 5 times, resulting in a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we take 325 away from 336, we end up with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 65

Advancing to step 5:
65 can be fit into 112 1 times, resulting in a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 251.0
The remainder is 47 after subtracting 65 from 112.
Take the next digit (1) from the dividend and append it to 47, then repeat: 471 / 65

On to step 6:
If we divide 471 by 65, we get 7 and a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 2517.0
If we take 455 away from 471, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
65 can be fit into 160 2 times, resulting in a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 2517.2
Deduct 130 from 160 and we're left 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.

Step 8:
300 divided by 65 is 4 with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 2517.24
The remainder is 40 after subtracting 260 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
65 goes into 400 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 2517.246
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
100 divided by 65 is 1 with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 2517.2461
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 11:
When dividing 350 by 65, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 2517.24615
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.

Going ahead to step 12:
The number 65 fits into 250 3 times, leaving a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 2517.246153
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.

On to step 13:
65 goes into 550 8 times with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 2517.2461538
Subtract 520 from 550 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
300 divided by 65 is 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 2517.24615384
The remainder is 40 after subtracting 260 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 2517.24615384 with a remaining 4e-08.
