We divide 19906020 by 905
We want to divide 19906020 by 905.

Going ahead to step 1:
If we divide 1 by 905, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 905

Moving on to step 2:
905 can be fit into 19 0 times, resulting in a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 905

Advancing to step 3:
When dividing 199 by 905, we get 0 with a remainder of 199.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 199 after subtracting 0 from 199.
Fetch the next digit (0) from the dividend, attach it to 199 and continue: 1990 / 905

Advancing to step 4:
905 can be fit into 1990 2 times, resulting in a remainder of 180.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1810 from 1990 to get 180.
Bring next digit (6) of the dividend behind the 180 and repeat the process: 1806 / 905

Step 5:
If we divide 1806 by 905, we get 1 and a remainder of 901.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 901 after subtracting 905 from 1806.
Grab the next digit (0) from the dividend, add it to 901, then carry on: 9010 / 905

On to step 6:
905 goes into 9010 9 times with a remainder of 865.
The number 9 becomes the next digit in our result. 
Result so far: 219.0
If we take 8145 away from 9010, we end up with 865.
Include the next digit (2) from the dividend after 865, then repeat: 8652 / 905

Step 7:
If we divide 8652 by 905, we get 9 and a remainder of 507.
Use 9 as the next digit of our solution. 
Result so far: 2199.0
The remainder is 507 after subtracting 8145 from 8652.
Append the next digit (0) from the dividend to 507 and continue with: 5070 / 905

Step 8:
905 can be fit into 5070 5 times, resulting in a remainder of 545.
Write down 5 as next digit of the result. 
Result so far: 21995.0
Subtracting 4525 from 5070 leaves us with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

On to step 9:
5450 divided by 905 is 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 21995.6
Deduct 5430 from 5450 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
If we divide 200 by 905, we get 0 and a remainder of 200.
The next digit of our result is 0. 
Result so far: 21995.6
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 11:
2000 divided by 905 is 2 with a remainder of 190.
Record the quotient 2 as the next digit in the result. 
Result so far: 21995.602
Subtracting 1810 from 2000 leaves us 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.

Step 12:
1900 divided by 905 is 2 with a remainder of 90.
Use 2 as the next digit of our solution. 
Result so far: 21995.6022
If we subtract 1810 from 1900, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The quotient of the division is 21995.6022, and the remainder is 0.0009.
