We look at the division of 1641 by 70 
We're looking to find how many times 70 goes into 1641.

Let's proceed to step 1:
70 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 70

Advancing to step 2:
If we divide 16 by 70, we get 0 and a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 70

Going ahead to step 3:
When dividing 164 by 70, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 140 from 164 leaves us with 24.
Take the next digit (1) from the dividend and append it to 24, then repeat: 241 / 70

Advancing to step 4:
If we divide 241 by 70, we get 3 and a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we take 210 away from 241, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 5:
When dividing 310 by 70, we get 4 with a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 23.4
If we take 280 away from 310, 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.

On to step 6:
300 divided by 70 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 23.44
Deduct 280 from 300 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.

After the division, we end up with 23.44 and a remainder of 0.02.
