We're dividing 21946890 by 388 
We want to figure out the number of times 21946890 can be divided by 388.

Advancing to step 1:
When dividing 2 by 388, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 388

Step 2:
The number 388 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 388

On to step 3:
388 goes into 219 0 times with a remainder of 219.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 219 leaves us with 219.
Include the next digit (4) from the dividend after 219, then repeat: 2194 / 388

Moving on to step 4:
The number 388 fits into 2194 5 times, leaving a remainder of 254.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 1940 from 2194 leaves us with 254.
Take the next digit (6) from the dividend and append it to 254, then repeat: 2546 / 388

Let's proceed to step 5:
If we divide 2546 by 388, we get 6 and a remainder of 218.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Subtracting 2328 from 2546 leaves us with 218.
Append the next digit (8) from the dividend to 218 and continue with: 2188 / 388

Going ahead to step 6:
If we divide 2188 by 388, we get 5 and a remainder of 248.
Write down 5 as next digit of the result. 
Result so far: 565.0
Subtracting 1940 from 2188 leaves us with 248.
Fetch the next digit (9) from the dividend, attach it to 248 and continue: 2489 / 388

Step 7:
388 goes into 2489 6 times with a remainder of 161.
Write down 6 as next digit of the result. 
Result so far: 5656.0
Subtracting 2328 from 2489 leaves us with 161.
Include the next digit (0) from the dividend after 161, then repeat: 1610 / 388

Going ahead to step 8:
388 goes into 1610 4 times with a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 56564.0
Subtract 1552 from 1610 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 9:
The number 388 fits into 580 1 times, leaving a remainder of 192.
Record the quotient 1 as the next digit in the result. 
Result so far: 56564.1
The remainder is 192 after subtracting 388 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 10:
388 goes into 1920 4 times with a remainder of 368.
The number 4 becomes the next digit in our result. 
Result so far: 56564.14
The remainder is 368 after subtracting 1552 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 11:
When dividing 3680 by 388, we get 9 with a remainder of 188.
The number 9 becomes the next digit in our result. 
Result so far: 56564.149
Subtract 3492 from 3680 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 12:
1880 divided by 388 is 4 with a remainder of 328.
The next digit of our result is 4. 
Result so far: 56564.1494
Subtract 1552 from 1880 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 13:
The number 388 fits into 3280 8 times, leaving a remainder of 176.
Record the quotient 8 as the next digit in the result. 
Result so far: 56564.14948
Subtracting 3104 from 3280 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 14:
If we divide 1760 by 388, we get 4 and a remainder of 208.
The number 4 becomes the next digit in our result. 
Result so far: 56564.149484
If we take 1552 away from 1760, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 15:
If we divide 2080 by 388, we get 5 and a remainder of 140.
Record the quotient 5 as the next digit in the result. 
Result so far: 56564.1494845
Subtract 1940 from 2080 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 16:
388 goes into 1400 3 times with a remainder of 236.
The next digit of our result is 3. 
Result so far: 56564.14948453
If we take 1164 away from 1400, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The quotient of the division is 56564.14948453, and the remainder is 2.36e-07.
