30492039 ÷ 402 
We want to divide 30492039 by 402.

Going ahead to step 1:
When dividing 3 by 402, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 402

Going ahead to step 2:
If we divide 30 by 402, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 402

Moving on to step 3:
If we divide 304 by 402, we get 0 and a remainder of 304.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 304 and we're left with 304.
Bring next digit (9) of the dividend behind the 304 and repeat the process: 3049 / 402

Let's proceed to step 4:
If we divide 3049 by 402, we get 7 and a remainder of 235.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 235 after subtracting 2814 from 3049.
Grab the next digit (2) from the dividend, add it to 235, then carry on: 2352 / 402

Moving on to step 5:
The number 402 fits into 2352 5 times, leaving a remainder of 342.
The next digit of our result is 5. 
Result so far: 75.0
Deduct 2010 from 2352 and we're left with 342.
Fetch the next digit (0) from the dividend, attach it to 342 and continue: 3420 / 402

Going ahead to step 6:
3420 divided by 402 is 8 with a remainder of 204.
Use 8 as the next digit of our solution. 
Result so far: 758.0
Subtract 3216 from 3420 to get 204.
Fetch the next digit (3) from the dividend, attach it to 204 and continue: 2043 / 402

On to step 7:
402 can be fit into 2043 5 times, resulting in a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 7585.0
Subtracting 2010 from 2043 leaves us with 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 402

Step 8:
339 divided by 402 is 0 with a remainder of 339.
The next digit of our result is 0. 
Result so far: 75850.0
Subtract 0 from 339 to get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Let's proceed to step 9:
When dividing 3390 by 402, we get 8 with a remainder of 174.
The number 8 becomes the next digit in our result. 
Result so far: 75850.8
Deduct 3216 from 3390 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 10:
The number 402 fits into 1740 4 times, leaving a remainder of 132.
The next digit of our result is 4. 
Result so far: 75850.84
Subtract 1608 from 1740 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 11:
402 goes into 1320 3 times with a remainder of 114.
The number 3 becomes the next digit in our result. 
Result so far: 75850.843
Subtracting 1206 from 1320 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 12:
The number 402 fits into 1140 2 times, leaving a remainder of 336.
Put 2 as the next digit of the answer. 
Result so far: 75850.8432
If we subtract 804 from 1140, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 13:
If we divide 3360 by 402, we get 8 and a remainder of 144.
Write down 8 as next digit of the result. 
Result so far: 75850.84328
Subtract 3216 from 3360 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 14:
If we divide 1440 by 402, we get 3 and a remainder of 234.
Write down 3 as next digit of the result. 
Result so far: 75850.843283
The remainder is 234 after subtracting 1206 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 15:
402 goes into 2340 5 times with a remainder of 330.
The number 5 becomes the next digit in our result. 
Result so far: 75850.8432835
If we take 2010 away from 2340, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 16:
402 can be fit into 3300 8 times, resulting in a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 75850.84328358
If we subtract 3216 from 3300, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final outcome is 75850.84328358, with a leftover of 8.4e-08.
