We're dividing 19225797 by 42 
We want to figure out the number of times 19225797 can be divided by 42.

Step 1:
1 divided by 42 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 42

On to step 2:
If we divide 19 by 42, we get 0 and a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 42

On to step 3:
192 divided by 42 is 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 168 from 192 and we're left with 24.
Take the next digit (2) from the dividend and append it to 24, then repeat: 242 / 42

Step 4:
If we divide 242 by 42, we get 5 and a remainder of 32.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtracting 210 from 242 leaves us with 32.
Grab the next digit (5) from the dividend, add it to 32, then carry on: 325 / 42

Going ahead to step 5:
42 can be fit into 325 7 times, resulting in a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 457.0
If we take 294 away from 325, we end up with 31.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 42

Going ahead to step 6:
42 can be fit into 317 7 times, resulting in a remainder of 23.
The next digit of our result is 7. 
Result so far: 4577.0
The remainder is 23 after subtracting 294 from 317.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 42

Advancing to step 7:
The number 42 fits into 239 5 times, leaving a remainder of 29.
Write down 5 as next digit of the result. 
Result so far: 45775.0
If we subtract 210 from 239, we get 29.
Bring next digit (7) of the dividend behind the 29 and repeat the process: 297 / 42

Let's proceed to step 8:
297 divided by 42 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 457757.0
Subtract 294 from 297 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
When dividing 30 by 42, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 457757.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 457757.07
Deduct 294 from 300 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
If we divide 60 by 42, we get 1 and a remainder of 18.
The next digit of our result is 1. 
Result so far: 457757.071
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 457757.0714
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 457757.07142
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
360 divided by 42 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 457757.071428
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 15:
240 divided by 42 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 457757.0714285
Deduct 210 from 240 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 16:
When dividing 300 by 42, we get 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 457757.07142857
Deduct 294 from 300 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 457757.07142857 with a remainder of 6e-09.
