We divide 3453 by 71
We want to figure out the number of times 3453 can be divided by 71.

Moving on to step 1:
If we divide 3 by 71, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 71

Let's proceed to step 2:
When dividing 34 by 71, we get 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 71

Moving on to step 3:
71 goes into 345 4 times with a remainder of 61.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 61 after subtracting 284 from 345.
Grab the next digit (3) from the dividend, add it to 61, then carry on: 613 / 71

Let's proceed to step 4:
If we divide 613 by 71, we get 8 and a remainder of 45.
The next digit of our result is 8. 
Result so far: 48.0
Subtract 568 from 613 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 5:
71 goes into 450 6 times with a remainder of 24.
The next digit of our result is 6. 
Result so far: 48.6
If we take 426 away from 450, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 6:
If we divide 240 by 71, we get 3 and a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 48.63
If we take 213 away from 240, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
When dividing 270 by 71, we get 3 with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 48.633
Deduct 213 from 270 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Our division results in 48.633 with a remaining 0.0057.
