21014204 ÷ 388 
Our goal is to divide 21014204 by 388.

Let's proceed to step 1:
388 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 388

Advancing to step 2:
The number 388 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 388

Let's proceed to step 3:
210 divided by 388 is 0 with a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 210 leaves us with 210.
Fetch the next digit (1) from the dividend, attach it to 210 and continue: 2101 / 388

Moving on to step 4:
388 goes into 2101 5 times with a remainder of 161.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 1940 from 2101, we get 161.
Append the next digit (4) from the dividend to 161 and continue with: 1614 / 388

Let's proceed to step 5:
The number 388 fits into 1614 4 times, leaving a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 54.0
If we take 1552 away from 1614, we end up with 62.
Grab the next digit (2) from the dividend, add it to 62, then carry on: 622 / 388

Advancing to step 6:
388 can be fit into 622 1 times, resulting in a remainder of 234.
Record the quotient 1 as the next digit in the result. 
Result so far: 541.0
Subtract 388 from 622 to get 234.
Fetch the next digit (0) from the dividend, attach it to 234 and continue: 2340 / 388

Moving on to step 7:
388 can be fit into 2340 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 5416.0
Subtracting 2328 from 2340 leaves us with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 388

Advancing to step 8:
388 can be fit into 124 0 times, resulting in a remainder of 124.
Record the quotient 0 as the next digit in the result. 
Result so far: 54160.0
If we take 0 away from 124, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 9:
When dividing 1240 by 388, we get 3 with a remainder of 76.
Use 3 as the next digit of our solution. 
Result so far: 54160.3
If we take 1164 away from 1240, we end up with 76.
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 10:
The number 388 fits into 760 1 times, leaving a remainder of 372.
Record the quotient 1 as the next digit in the result. 
Result so far: 54160.31
Deduct 388 from 760 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Advancing to step 11:
The number 388 fits into 3720 9 times, leaving a remainder of 228.
Use 9 as the next digit of our solution. 
Result so far: 54160.319
If we take 3492 away from 3720, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 12:
2280 divided by 388 is 5 with a remainder of 340.
The number 5 becomes the next digit in our result. 
Result so far: 54160.3195
If we take 1940 away from 2280, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 13:
The number 388 fits into 3400 8 times, leaving a remainder of 296.
Record the quotient 8 as the next digit in the result. 
Result so far: 54160.31958
The remainder is 296 after subtracting 3104 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 14:
388 goes into 2960 7 times with a remainder of 244.
Use 7 as the next digit of our solution. 
Result so far: 54160.319587
Subtract 2716 from 2960 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 15:
2440 divided by 388 is 6 with a remainder of 112.
Put 6 as the next digit of the answer. 
Result so far: 54160.3195876
Subtracting 2328 from 2440 leaves us 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.

Step 16:
When dividing 1120 by 388, we get 2 with a remainder of 344.
Put 2 as the next digit of the answer. 
Result so far: 54160.31958762
Subtract 776 from 1120 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

In conclusion, the division gives 54160.31958762 with a balance of 3.44e-07.
