398550 ÷ 71 
We want to figure out the number of times 398550 can be divided by 71.

Moving on to step 1:
When dividing 3 by 71, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 71

Moving on to step 2:
The number 71 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 71

Advancing to step 3:
71 can be fit into 398 5 times, resulting in a remainder of 43.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 43 after subtracting 355 from 398.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 71

Advancing to step 4:
71 goes into 435 6 times with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 56.0
If we subtract 426 from 435, we get 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 71

Advancing to step 5:
When dividing 95 by 71, we get 1 with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 561.0
If we take 71 away from 95, we end up with 24.
Fetch the next digit (0) from the dividend, attach it to 24 and continue: 240 / 71

Step 6:
The number 71 fits into 240 3 times, leaving a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 5613.0
Subtract 213 from 240 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
71 can be fit into 270 3 times, resulting in a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 5613.3
If we take 213 away from 270, we end up 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.

Going ahead to step 8:
When dividing 570 by 71, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 5613.38
The remainder is 2 after subtracting 568 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
71 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 5613.38
Subtracting 0 from 20 leaves us 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.

Advancing to step 10:
The number 71 fits into 200 2 times, leaving a remainder of 58.
The next digit of our result is 2. 
Result so far: 5613.3802
Subtracting 142 from 200 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 11:
If we divide 580 by 71, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 5613.38028
If we take 568 away from 580, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
The number 71 fits into 120 1 times, leaving a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 5613.380281
Subtracting 71 from 120 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 13:
If we divide 490 by 71, we get 6 and a remainder of 64.
The next digit of our result is 6. 
Result so far: 5613.3802816
If we subtract 426 from 490, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 14:
If we divide 640 by 71, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 5613.38028169
Subtract 639 from 640 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 5613.38028169 with a remainder of 1e-09.
