Let's divide 19636432 by 490
We want to figure out the number of times 19636432 can be divided by 490.

Step 1:
490 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 490

On to step 2:
When dividing 19 by 490, we get 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 490

On to step 3:
196 divided by 490 is 0 with a remainder of 196.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 196 and we're left with 196.
Append the next digit (3) from the dividend to 196 and continue with: 1963 / 490

Going ahead to step 4:
490 goes into 1963 4 times with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 1960 from 1963 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 490

On to step 5:
490 goes into 36 0 times with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Deduct 0 from 36 and we're left with 36.
Grab the next digit (4) from the dividend, add it to 36, then carry on: 364 / 490

On to step 6:
The number 490 fits into 364 0 times, leaving a remainder of 364.
Record the quotient 0 as the next digit in the result. 
Result so far: 400.0
If we subtract 0 from 364, we get 364.
Bring next digit (3) of the dividend behind the 364 and repeat the process: 3643 / 490

Step 7:
When dividing 3643 by 490, we get 7 with a remainder of 213.
The number 7 becomes the next digit in our result. 
Result so far: 4007.0
The remainder is 213 after subtracting 3430 from 3643.
Grab the next digit (2) from the dividend, add it to 213, then carry on: 2132 / 490

Going ahead to step 8:
490 can be fit into 2132 4 times, resulting in a remainder of 172.
Write down 4 as next digit of the result. 
Result so far: 40074.0
If we take 1960 away from 2132, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 9:
490 goes into 1720 3 times with a remainder of 250.
Put 3 as the next digit of the answer. 
Result so far: 40074.3
If we take 1470 away from 1720, 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.

Let's proceed to step 10:
If we divide 2500 by 490, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 40074.35
If we subtract 2450 from 2500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
The number 490 fits into 500 1 times, leaving a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 40074.351
If we subtract 490 from 500, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
When dividing 100 by 490, we get 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 40074.351
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 13:
If we divide 1000 by 490, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 40074.35102
If we subtract 980 from 1000, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
When dividing 200 by 490, we get 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 40074.35102
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 15:
490 can be fit into 2000 4 times, resulting in a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 40074.3510204
Subtracting 1960 from 2000 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 16:
If we divide 400 by 490, we get 0 and a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 40074.3510204
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 40074.3510204 with a remainder of 4e-07.
