22989002 ÷ 578 
We're looking to find how many times 578 goes into 22989002.

On to step 1:
When dividing 2 by 578, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 578

Step 2:
The number 578 fits into 22 0 times, leaving a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 578

Advancing to step 3:
When dividing 229 by 578, we get 0 with a remainder of 229.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 229 and we're left with 229.
Append the next digit (8) from the dividend to 229 and continue with: 2298 / 578

On to step 4:
The number 578 fits into 2298 3 times, leaving a remainder of 564.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 1734 from 2298, we get 564.
Bring next digit (9) of the dividend behind the 564 and repeat the process: 5649 / 578

Step 5:
5649 divided by 578 is 9 with a remainder of 447.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we take 5202 away from 5649, we end up with 447.
Include the next digit (0) from the dividend after 447, then repeat: 4470 / 578

On to step 6:
578 goes into 4470 7 times with a remainder of 424.
Put 7 as the next digit of the answer. 
Result so far: 397.0
If we take 4046 away from 4470, we end up with 424.
Bring next digit (0) of the dividend behind the 424 and repeat the process: 4240 / 578

Advancing to step 7:
When dividing 4240 by 578, we get 7 with a remainder of 194.
The next digit of our result is 7. 
Result so far: 3977.0
Subtracting 4046 from 4240 leaves us with 194.
Include the next digit (2) from the dividend after 194, then repeat: 1942 / 578

On to step 8:
578 goes into 1942 3 times with a remainder of 208.
The next digit of our result is 3. 
Result so far: 39773.0
If we subtract 1734 from 1942, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 9:
2080 divided by 578 is 3 with a remainder of 346.
Use 3 as the next digit of our solution. 
Result so far: 39773.3
Subtract 1734 from 2080 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

On to step 10:
If we divide 3460 by 578, we get 5 and a remainder of 570.
Put 5 as the next digit of the answer. 
Result so far: 39773.35
Deduct 2890 from 3460 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Moving on to step 11:
5700 divided by 578 is 9 with a remainder of 498.
Record the quotient 9 as the next digit in the result. 
Result so far: 39773.359
If we take 5202 away from 5700, we end up with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

On to step 12:
When dividing 4980 by 578, we get 8 with a remainder of 356.
Write down 8 as next digit of the result. 
Result so far: 39773.3598
If we subtract 4624 from 4980, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 13:
578 goes into 3560 6 times with a remainder of 92.
The number 6 becomes the next digit in our result. 
Result so far: 39773.35986
If we subtract 3468 from 3560, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 14:
When dividing 920 by 578, we get 1 with a remainder of 342.
The next digit of our result is 1. 
Result so far: 39773.359861
If we subtract 578 from 920, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 15:
3420 divided by 578 is 5 with a remainder of 530.
Use 5 as the next digit of our solution. 
Result so far: 39773.3598615
Subtract 2890 from 3420 to get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Going ahead to step 16:
When dividing 5300 by 578, we get 9 with a remainder of 98.
The next digit of our result is 9. 
Result so far: 39773.35986159
Deduct 5202 from 5300 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

The final outcome is 39773.35986159, with a leftover of 9.8e-08.
