30456172 ÷ 402 
We want to divide 30456172 by 402.

On to step 1:
3 divided by 402 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 402

Going ahead to step 2:
402 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 402

Going ahead to step 3:
If we divide 304 by 402, we get 0 and a remainder of 304.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 304 and we're left with 304.
Take the next digit (5) from the dividend and append it to 304, then repeat: 3045 / 402

On to step 4:
When dividing 3045 by 402, we get 7 with a remainder of 231.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 2814 from 3045 leaves us with 231.
Append the next digit (6) from the dividend to 231 and continue with: 2316 / 402

Let's proceed to step 5:
If we divide 2316 by 402, we get 5 and a remainder of 306.
Use 5 as the next digit of our solution. 
Result so far: 75.0
Subtracting 2010 from 2316 leaves us with 306.
Include the next digit (1) from the dividend after 306, then repeat: 3061 / 402

Let's proceed to step 6:
When dividing 3061 by 402, we get 7 with a remainder of 247.
The number 7 becomes the next digit in our result. 
Result so far: 757.0
If we take 2814 away from 3061, we end up with 247.
Include the next digit (7) from the dividend after 247, then repeat: 2477 / 402

Step 7:
402 goes into 2477 6 times with a remainder of 65.
Record the quotient 6 as the next digit in the result. 
Result so far: 7576.0
Deduct 2412 from 2477 and we're left with 65.
Include the next digit (2) from the dividend after 65, then repeat: 652 / 402

Moving on to step 8:
652 divided by 402 is 1 with a remainder of 250.
Record the quotient 1 as the next digit in the result. 
Result so far: 75761.0
If we take 402 away from 652, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 9:
2500 divided by 402 is 6 with a remainder of 88.
Put 6 as the next digit of the answer. 
Result so far: 75761.6
Deduct 2412 from 2500 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 10:
402 goes into 880 2 times with a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 75761.62
Deduct 804 from 880 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 11:
402 goes into 760 1 times with a remainder of 358.
Write down 1 as next digit of the result. 
Result so far: 75761.621
If we take 402 away from 760, we end up with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Advancing to step 12:
402 can be fit into 3580 8 times, resulting in a remainder of 364.
The number 8 becomes the next digit in our result. 
Result so far: 75761.6218
The remainder is 364 after subtracting 3216 from 3580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 13:
If we divide 3640 by 402, we get 9 and a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 75761.62189
The remainder is 22 after subtracting 3618 from 3640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
220 divided by 402 is 0 with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 75761.62189
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 15:
The number 402 fits into 2200 5 times, leaving a remainder of 190.
Use 5 as the next digit of our solution. 
Result so far: 75761.6218905
Subtract 2010 from 2200 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 16:
When dividing 1900 by 402, we get 4 with a remainder of 292.
Put 4 as the next digit of the answer. 
Result so far: 75761.62189054
Subtracting 1608 from 1900 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

After the division, we end up with 75761.62189054 and a remainder of 2.92e-07.
