We look at the division of 17905972 by 402 
We want to figure out the number of times 17905972 can be divided by 402.

Step 1:
402 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 402

Going ahead to step 2:
402 can be fit into 17 0 times, resulting in a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 402

Advancing to step 3:
179 divided by 402 is 0 with a remainder of 179.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 179, we get 179.
Bring next digit (0) of the dividend behind the 179 and repeat the process: 1790 / 402

Let's proceed to step 4:
The number 402 fits into 1790 4 times, leaving a remainder of 182.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 1608 away from 1790, we end up with 182.
Include the next digit (5) from the dividend after 182, then repeat: 1825 / 402

Moving on to step 5:
402 goes into 1825 4 times with a remainder of 217.
The next digit of our result is 4. 
Result so far: 44.0
Subtracting 1608 from 1825 leaves us with 217.
Take the next digit (9) from the dividend and append it to 217, then repeat: 2179 / 402

Advancing to step 6:
402 can be fit into 2179 5 times, resulting in a remainder of 169.
Record the quotient 5 as the next digit in the result. 
Result so far: 445.0
Subtract 2010 from 2179 to get 169.
Grab the next digit (7) from the dividend, add it to 169, then carry on: 1697 / 402

Going ahead to step 7:
When dividing 1697 by 402, we get 4 with a remainder of 89.
Put 4 as the next digit of the answer. 
Result so far: 4454.0
The remainder is 89 after subtracting 1608 from 1697.
Fetch the next digit (2) from the dividend, attach it to 89 and continue: 892 / 402

On to step 8:
892 divided by 402 is 2 with a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 44542.0
Subtracting 804 from 892 leaves us 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.

Going ahead to step 9:
If we divide 880 by 402, we get 2 and a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 44542.2
If we subtract 804 from 880, we get 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 10:
The number 402 fits into 760 1 times, leaving a remainder of 358.
Write down 1 as next digit of the result. 
Result so far: 44542.21
Subtracting 402 from 760 leaves us 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 11:
When dividing 3580 by 402, we get 8 with a remainder of 364.
Use 8 as the next digit of our solution. 
Result so far: 44542.218
Subtracting 3216 from 3580 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 12:
The number 402 fits into 3640 9 times, leaving a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 44542.2189
Subtract 3618 from 3640 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
402 goes into 220 0 times with a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 44542.2189
If we subtract 0 from 220, we 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 14:
The number 402 fits into 2200 5 times, leaving a remainder of 190.
Write down 5 as next digit of the result. 
Result so far: 44542.218905
Deduct 2010 from 2200 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 15:
402 can be fit into 1900 4 times, resulting in a remainder of 292.
Put 4 as the next digit of the answer. 
Result so far: 44542.2189054
If we subtract 1608 from 1900, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 16:
When dividing 2920 by 402, we get 7 with a remainder of 106.
The next digit of our result is 7. 
Result so far: 44542.21890547
Subtract 2814 from 2920 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

The quotient of the division is 44542.21890547, and the remainder is 1.06e-07.
