We look at the division of 45405072 by 71 
We want to divide 45405072 by 71.

Going ahead to step 1:
71 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 71

Moving on to step 2:
The number 71 fits into 45 0 times, leaving a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Append the next digit (4) from the dividend to 45 and continue with: 454 / 71

Moving on to step 3:
The number 71 fits into 454 6 times, leaving a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 426 from 454 and we're left with 28.
Bring next digit (0) of the dividend behind the 28 and repeat the process: 280 / 71

Let's proceed to step 4:
280 divided by 71 is 3 with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
Subtract 213 from 280 to get 67.
Include the next digit (5) from the dividend after 67, then repeat: 675 / 71

Let's proceed to step 5:
If we divide 675 by 71, we get 9 and a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 639.0
Subtract 639 from 675 to get 36.
Include the next digit (0) from the dividend after 36, then repeat: 360 / 71

Let's proceed to step 6:
71 can be fit into 360 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 6395.0
The remainder is 5 after subtracting 355 from 360.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 71

On to step 7:
57 divided by 71 is 0 with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 63950.0
Deduct 0 from 57 and we're left with 57.
Grab the next digit (2) from the dividend, add it to 57, then carry on: 572 / 71

Advancing to step 8:
71 can be fit into 572 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 639508.0
If we take 568 away from 572, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
If we divide 40 by 71, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 639508.0
Deduct 0 from 40 and we're left with 40.
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 10:
The number 71 fits into 400 5 times, leaving a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 639508.05
Subtract 355 from 400 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.

On to step 11:
71 goes into 450 6 times with a remainder of 24.
The next digit of our result is 6. 
Result so far: 639508.056
Subtract 426 from 450 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
When dividing 240 by 71, we get 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 639508.0563
The remainder is 27 after subtracting 213 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 13:
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: 639508.05633
Subtract 213 from 270 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

After the division, we end up with 639508.05633 and a remainder of 5.7e-05.
