Let's see how many times 978 fits into 21658232.

Advancing to step 1:
If we divide 2 by 978, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 978

On to step 2:
When dividing 21 by 978, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 978

Step 3:
978 goes into 216 0 times with a remainder of 216.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 216 to get 216.
Take the next digit (5) from the dividend and append it to 216, then repeat: 2165 / 978

Moving on to step 4:
978 goes into 2165 2 times with a remainder of 209.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1956 from 2165 to get 209.
Take the next digit (8) from the dividend and append it to 209, then repeat: 2098 / 978

Moving on to step 5:
If we divide 2098 by 978, we get 2 and a remainder of 142.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 1956 from 2098 to get 142.
Fetch the next digit (2) from the dividend, attach it to 142 and continue: 1422 / 978

Advancing to step 6:
1422 divided by 978 is 1 with a remainder of 444.
Put 1 as the next digit of the answer. 
Result so far: 221.0
The remainder is 444 after subtracting 978 from 1422.
Include the next digit (3) from the dividend after 444, then repeat: 4443 / 978

Step 7:
978 goes into 4443 4 times with a remainder of 531.
The next digit of our result is 4. 
Result so far: 2214.0
The remainder is 531 after subtracting 3912 from 4443.
Include the next digit (2) from the dividend after 531, then repeat: 5312 / 978

On to step 8:
If we divide 5312 by 978, we get 5 and a remainder of 422.
Put 5 as the next digit of the answer. 
Result so far: 22145.0
Subtracting 4890 from 5312 leaves us with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Moving on to step 9:
978 goes into 4220 4 times with a remainder of 308.
Record the quotient 4 as the next digit in the result. 
Result so far: 22145.4
Subtract 3912 from 4220 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 10:
978 can be fit into 3080 3 times, resulting in a remainder of 146.
Write down 3 as next digit of the result. 
Result so far: 22145.43
Deduct 2934 from 3080 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 11:
If we divide 1460 by 978, we get 1 and a remainder of 482.
The next digit of our result is 1. 
Result so far: 22145.431
Subtracting 978 from 1460 leaves us with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

On to step 12:
The number 978 fits into 4820 4 times, leaving a remainder of 908.
The number 4 becomes the next digit in our result. 
Result so far: 22145.4314
If we subtract 3912 from 4820, we get 908.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9080, and continue the process.

Going ahead to step 13:
978 can be fit into 9080 9 times, resulting in a remainder of 278.
The next digit of our result is 9. 
Result so far: 22145.43149
Subtract 8802 from 9080 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

On to step 14:
When dividing 2780 by 978, we get 2 with a remainder of 824.
The number 2 becomes the next digit in our result. 
Result so far: 22145.431492
The remainder is 824 after subtracting 1956 from 2780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

Let's proceed to step 15:
978 goes into 8240 8 times with a remainder of 416.
The next digit of our result is 8. 
Result so far: 22145.4314928
Subtract 7824 from 8240 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 16:
4160 divided by 978 is 4 with a remainder of 248.
Record the quotient 4 as the next digit in the result. 
Result so far: 22145.43149284
Deduct 3912 from 4160 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Our division results in 22145.43149284 with a remaining 2.48e-07.
