We're dividing 21930448 by 558 
We're looking to find how many times 558 goes into 21930448.

On to step 1:
If we divide 2 by 558, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 558

Going ahead to step 2:
When dividing 21 by 558, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 558

Step 3:
558 goes into 219 0 times with a remainder of 219.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 219 and we're left with 219.
Include the next digit (3) from the dividend after 219, then repeat: 2193 / 558

Going ahead to step 4:
The number 558 fits into 2193 3 times, leaving a remainder of 519.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 1674 from 2193 leaves us with 519.
Take the next digit (0) from the dividend and append it to 519, then repeat: 5190 / 558

Advancing to step 5:
If we divide 5190 by 558, we get 9 and a remainder of 168.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we subtract 5022 from 5190, we get 168.
Fetch the next digit (4) from the dividend, attach it to 168 and continue: 1684 / 558

Moving on to step 6:
If we divide 1684 by 558, we get 3 and a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 393.0
Subtract 1674 from 1684 to get 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 558

Advancing to step 7:
If we divide 104 by 558, we get 0 and a remainder of 104.
Write down 0 as next digit of the result. 
Result so far: 3930.0
Subtract 0 from 104 to get 104.
Take the next digit (8) from the dividend and append it to 104, then repeat: 1048 / 558

Step 8:
If we divide 1048 by 558, we get 1 and a remainder of 490.
The next digit of our result is 1. 
Result so far: 39301.0
Subtract 558 from 1048 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 9:
If we divide 4900 by 558, we get 8 and a remainder of 436.
The number 8 becomes the next digit in our result. 
Result so far: 39301.8
Subtract 4464 from 4900 to get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Step 10:
4360 divided by 558 is 7 with a remainder of 454.
Put 7 as the next digit of the answer. 
Result so far: 39301.87
Deduct 3906 from 4360 and we're left with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

On to step 11:
558 can be fit into 4540 8 times, resulting in a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 39301.878
The remainder is 76 after subtracting 4464 from 4540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 12:
558 can be fit into 760 1 times, resulting in a remainder of 202.
Write down 1 as next digit of the result. 
Result so far: 39301.8781
If we subtract 558 from 760, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 13:
The number 558 fits into 2020 3 times, leaving a remainder of 346.
Put 3 as the next digit of the answer. 
Result so far: 39301.87813
If we take 1674 away from 2020, we end up with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Advancing to step 14:
If we divide 3460 by 558, we get 6 and a remainder of 112.
Record the quotient 6 as the next digit in the result. 
Result so far: 39301.878136
If we take 3348 away from 3460, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 15:
1120 divided by 558 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 39301.8781362
Subtracting 1116 from 1120 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 16:
The number 558 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 39301.8781362
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 39301.8781362 with a balance of 4e-08.
