We look at the division of 30036388 by 402 
Let's see how many times 402 fits into 30036388.

Advancing to step 1:
402 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 402

Let's proceed to step 2:
When dividing 30 by 402, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 402

Step 3:
If we divide 300 by 402, we get 0 and a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 300 and we're left with 300.
Take the next digit (3) from the dividend and append it to 300, then repeat: 3003 / 402

Advancing to step 4:
3003 divided by 402 is 7 with a remainder of 189.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 2814 from 3003 and we're left with 189.
Bring next digit (6) of the dividend behind the 189 and repeat the process: 1896 / 402

Let's proceed to step 5:
If we divide 1896 by 402, we get 4 and a remainder of 288.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
If we subtract 1608 from 1896, we get 288.
Take the next digit (3) from the dividend and append it to 288, then repeat: 2883 / 402

Advancing to step 6:
The number 402 fits into 2883 7 times, leaving a remainder of 69.
Use 7 as the next digit of our solution. 
Result so far: 747.0
Subtract 2814 from 2883 to get 69.
Grab the next digit (8) from the dividend, add it to 69, then carry on: 698 / 402

Moving on to step 7:
402 goes into 698 1 times with a remainder of 296.
The number 1 becomes the next digit in our result. 
Result so far: 7471.0
Subtract 402 from 698 to get 296.
Include the next digit (8) from the dividend after 296, then repeat: 2968 / 402

Advancing to step 8:
When dividing 2968 by 402, we get 7 with a remainder of 154.
Put 7 as the next digit of the answer. 
Result so far: 74717.0
Subtracting 2814 from 2968 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 9:
402 can be fit into 1540 3 times, resulting in a remainder of 334.
Use 3 as the next digit of our solution. 
Result so far: 74717.3
If we take 1206 away from 1540, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 10:
402 goes into 3340 8 times with a remainder of 124.
Put 8 as the next digit of the answer. 
Result so far: 74717.38
Subtract 3216 from 3340 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 11:
If we divide 1240 by 402, we get 3 and a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 74717.383
Deduct 1206 from 1240 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 12:
When dividing 340 by 402, we get 0 with a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 74717.383
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 13:
402 goes into 3400 8 times with a remainder of 184.
The number 8 becomes the next digit in our result. 
Result so far: 74717.38308
Deduct 3216 from 3400 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 14:
If we divide 1840 by 402, we get 4 and a remainder of 232.
Write down 4 as next digit of the result. 
Result so far: 74717.383084
Subtracting 1608 from 1840 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 15:
The number 402 fits into 2320 5 times, leaving a remainder of 310.
Record the quotient 5 as the next digit in the result. 
Result so far: 74717.3830845
The remainder is 310 after subtracting 2010 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 16:
402 goes into 3100 7 times with a remainder of 286.
Write down 7 as next digit of the result. 
Result so far: 74717.38308457
If we subtract 2814 from 3100, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Our division results in 74717.38308457 with a remaining 2.86e-07.
