22227937 divided by 646 
We want to figure out the number of times 22227937 can be divided by 646.

Advancing to step 1:
2 divided by 646 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 646

Step 2:
If we divide 22 by 646, we get 0 and a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 646

Step 3:
The number 646 fits into 222 0 times, leaving a remainder of 222.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 222 leaves us with 222.
Fetch the next digit (2) from the dividend, attach it to 222 and continue: 2222 / 646

On to step 4:
646 can be fit into 2222 3 times, resulting in a remainder of 284.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 1938 from 2222 leaves us with 284.
Take the next digit (7) from the dividend and append it to 284, then repeat: 2847 / 646

Let's proceed to step 5:
The number 646 fits into 2847 4 times, leaving a remainder of 263.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtracting 2584 from 2847 leaves us with 263.
Fetch the next digit (9) from the dividend, attach it to 263 and continue: 2639 / 646

Step 6:
The number 646 fits into 2639 4 times, leaving a remainder of 55.
Use 4 as the next digit of our solution. 
Result so far: 344.0
Subtracting 2584 from 2639 leaves us with 55.
Append the next digit (3) from the dividend to 55 and continue with: 553 / 646

Let's proceed to step 7:
When dividing 553 by 646, we get 0 with a remainder of 553.
Write down 0 as next digit of the result. 
Result so far: 3440.0
If we subtract 0 from 553, we get 553.
Include the next digit (7) from the dividend after 553, then repeat: 5537 / 646

Moving on to step 8:
646 goes into 5537 8 times with a remainder of 369.
The next digit of our result is 8. 
Result so far: 34408.0
The remainder is 369 after subtracting 5168 from 5537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Step 9:
3690 divided by 646 is 5 with a remainder of 460.
The next digit of our result is 5. 
Result so far: 34408.5
Subtracting 3230 from 3690 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 10:
646 can be fit into 4600 7 times, resulting in a remainder of 78.
The next digit of our result is 7. 
Result so far: 34408.57
Subtracting 4522 from 4600 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 11:
The number 646 fits into 780 1 times, leaving a remainder of 134.
Write down 1 as next digit of the result. 
Result so far: 34408.571
Subtracting 646 from 780 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 12:
If we divide 1340 by 646, we get 2 and a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 34408.5712
Deduct 1292 from 1340 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
480 divided by 646 is 0 with a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 34408.5712
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 14:
When dividing 4800 by 646, we get 7 with a remainder of 278.
Write down 7 as next digit of the result. 
Result so far: 34408.571207
Deduct 4522 from 4800 and we're left with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Moving on to step 15:
646 can be fit into 2780 4 times, resulting in a remainder of 196.
The number 4 becomes the next digit in our result. 
Result so far: 34408.5712074
If we subtract 2584 from 2780, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 16:
1960 divided by 646 is 3 with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 34408.57120743
If we subtract 1938 from 1960, we 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.

The final outcome is 34408.57120743, with a leftover of 2.2e-08.
