Let's divide 71489781 by 402
We're looking to find how many times 402 goes into 71489781.

On to step 1:
402 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 402

Let's proceed to step 2:
402 can be fit into 71 0 times, resulting in a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Fetch the next digit (4) from the dividend, attach it to 71 and continue: 714 / 402

On to step 3:
402 goes into 714 1 times with a remainder of 312.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 402 from 714 and we're left with 312.
Fetch the next digit (8) from the dividend, attach it to 312 and continue: 3128 / 402

Step 4:
When dividing 3128 by 402, we get 7 with a remainder of 314.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 2814 from 3128 to get 314.
Bring next digit (9) of the dividend behind the 314 and repeat the process: 3149 / 402

Step 5:
402 goes into 3149 7 times with a remainder of 335.
The number 7 becomes the next digit in our result. 
Result so far: 177.0
Subtract 2814 from 3149 to get 335.
Include the next digit (7) from the dividend after 335, then repeat: 3357 / 402

Going ahead to step 6:
3357 divided by 402 is 8 with a remainder of 141.
Use 8 as the next digit of our solution. 
Result so far: 1778.0
If we take 3216 away from 3357, we end up with 141.
Append the next digit (8) from the dividend to 141 and continue with: 1418 / 402

On to step 7:
1418 divided by 402 is 3 with a remainder of 212.
Put 3 as the next digit of the answer. 
Result so far: 17783.0
Subtracting 1206 from 1418 leaves us with 212.
Fetch the next digit (1) from the dividend, attach it to 212 and continue: 2121 / 402

Going ahead to step 8:
The number 402 fits into 2121 5 times, leaving a remainder of 111.
The next digit of our result is 5. 
Result so far: 177835.0
If we subtract 2010 from 2121, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 9:
1110 divided by 402 is 2 with a remainder of 306.
Use 2 as the next digit of our solution. 
Result so far: 177835.2
The remainder is 306 after subtracting 804 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 10:
3060 divided by 402 is 7 with a remainder of 246.
Put 7 as the next digit of the answer. 
Result so far: 177835.27
Subtracting 2814 from 3060 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 11:
If we divide 2460 by 402, we get 6 and a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 177835.276
Deduct 2412 from 2460 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
402 can be fit into 480 1 times, resulting in a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 177835.2761
Deduct 402 from 480 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 13:
780 divided by 402 is 1 with a remainder of 378.
Use 1 as the next digit of our solution. 
Result so far: 177835.27611
If we take 402 away from 780, we end up with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Our division results in 177835.27611 with a remaining 0.000378.
