18872468 ÷ 402 
Our goal is to divide 18872468 by 402.

Advancing to step 1:
1 divided by 402 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 402

Advancing to step 2:
The number 402 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 402

Going ahead to step 3:
402 can be fit into 188 0 times, resulting in a remainder of 188.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 188 after subtracting 0 from 188.
Take the next digit (7) from the dividend and append it to 188, then repeat: 1887 / 402

Step 4:
When dividing 1887 by 402, we get 4 with a remainder of 279.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 1608 from 1887 leaves us with 279.
Grab the next digit (2) from the dividend, add it to 279, then carry on: 2792 / 402

Going ahead to step 5:
2792 divided by 402 is 6 with a remainder of 380.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we subtract 2412 from 2792, we get 380.
Grab the next digit (4) from the dividend, add it to 380, then carry on: 3804 / 402

Let's proceed to step 6:
When dividing 3804 by 402, we get 9 with a remainder of 186.
Write down 9 as next digit of the result. 
Result so far: 469.0
Deduct 3618 from 3804 and we're left with 186.
Include the next digit (6) from the dividend after 186, then repeat: 1866 / 402

Advancing to step 7:
If we divide 1866 by 402, we get 4 and a remainder of 258.
Write down 4 as next digit of the result. 
Result so far: 4694.0
The remainder is 258 after subtracting 1608 from 1866.
Fetch the next digit (8) from the dividend, attach it to 258 and continue: 2588 / 402

Moving on to step 8:
402 can be fit into 2588 6 times, resulting in a remainder of 176.
Use 6 as the next digit of our solution. 
Result so far: 46946.0
If we take 2412 away from 2588, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 9:
When dividing 1760 by 402, we get 4 with a remainder of 152.
Write down 4 as next digit of the result. 
Result so far: 46946.4
Subtract 1608 from 1760 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 10:
If we divide 1520 by 402, we get 3 and a remainder of 314.
Write down 3 as next digit of the result. 
Result so far: 46946.43
If we subtract 1206 from 1520, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

On to step 11:
The number 402 fits into 3140 7 times, leaving a remainder of 326.
Use 7 as the next digit of our solution. 
Result so far: 46946.437
Subtract 2814 from 3140 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Moving on to step 12:
If we divide 3260 by 402, we get 8 and a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 46946.4378
If we subtract 3216 from 3260, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
The number 402 fits into 440 1 times, leaving a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 46946.43781
Subtracting 402 from 440 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 14:
The number 402 fits into 380 0 times, leaving a remainder of 380.
The next digit of our result is 0. 
Result so far: 46946.43781
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 15:
When dividing 3800 by 402, we get 9 with a remainder of 182.
Use 9 as the next digit of our solution. 
Result so far: 46946.4378109
Deduct 3618 from 3800 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 16:
402 can be fit into 1820 4 times, resulting in a remainder of 212.
The next digit of our result is 4. 
Result so far: 46946.43781094
Subtract 1608 from 1820 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Our division results in 46946.43781094 with a remaining 2.12e-07.
