19649596 ÷ 820 
We want to figure out the number of times 19649596 can be divided by 820.

On to step 1:
When dividing 1 by 820, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 820

On to step 2:
When dividing 19 by 820, we get 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 820

On to step 3:
When dividing 196 by 820, we get 0 with a remainder of 196.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 196 and we're left with 196.
Include the next digit (4) from the dividend after 196, then repeat: 1964 / 820

Going ahead to step 4:
1964 divided by 820 is 2 with a remainder of 324.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 1640 from 1964, we get 324.
Append the next digit (9) from the dividend to 324 and continue with: 3249 / 820

Moving on to step 5:
If we divide 3249 by 820, we get 3 and a remainder of 789.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we subtract 2460 from 3249, we get 789.
Include the next digit (5) from the dividend after 789, then repeat: 7895 / 820

Going ahead to step 6:
820 can be fit into 7895 9 times, resulting in a remainder of 515.
The next digit of our result is 9. 
Result so far: 239.0
The remainder is 515 after subtracting 7380 from 7895.
Grab the next digit (9) from the dividend, add it to 515, then carry on: 5159 / 820

Moving on to step 7:
The number 820 fits into 5159 6 times, leaving a remainder of 239.
The number 6 becomes the next digit in our result. 
Result so far: 2396.0
The remainder is 239 after subtracting 4920 from 5159.
Include the next digit (6) from the dividend after 239, then repeat: 2396 / 820

Advancing to step 8:
820 goes into 2396 2 times with a remainder of 756.
The next digit of our result is 2. 
Result so far: 23962.0
Subtract 1640 from 2396 to get 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Let's proceed to step 9:
The number 820 fits into 7560 9 times, leaving a remainder of 180.
Write down 9 as next digit of the result. 
Result so far: 23962.9
Subtracting 7380 from 7560 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 10:
1800 divided by 820 is 2 with a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 23962.92
Subtract 1640 from 1800 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 11:
820 goes into 1600 1 times with a remainder of 780.
The next digit of our result is 1. 
Result so far: 23962.921
If we subtract 820 from 1600, we get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Advancing to step 12:
The number 820 fits into 7800 9 times, leaving a remainder of 420.
Write down 9 as next digit of the result. 
Result so far: 23962.9219
The remainder is 420 after subtracting 7380 from 7800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 13:
820 can be fit into 4200 5 times, resulting in a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 23962.92195
Subtract 4100 from 4200 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 14:
If we divide 1000 by 820, we get 1 and a remainder of 180.
Record the quotient 1 as the next digit in the result. 
Result so far: 23962.921951
If we take 820 away from 1000, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 15:
If we divide 1800 by 820, we get 2 and a remainder of 160.
Record the quotient 2 as the next digit in the result. 
Result so far: 23962.9219512
Deduct 1640 from 1800 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 16:
820 goes into 1600 1 times with a remainder of 780.
Write down 1 as next digit of the result. 
Result so far: 23962.92195121
Subtracting 820 from 1600 leaves us with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

After the division, we end up with 23962.92195121 and a remainder of 7.8e-07.
