38967132 divided by 21 
Our goal is to divide 38967132 by 21.

Going ahead to step 1:
When dividing 3 by 21, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 21

Let's proceed to step 2:
38 divided by 21 is 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 21 from 38 and we're left with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 21

Going ahead to step 3:
If we divide 179 by 21, we get 8 and a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 168 from 179, we get 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 21

Advancing to step 4:
21 can be fit into 116 5 times, resulting in a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 185.0
Deduct 105 from 116 and we're left with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 21

On to step 5:
The number 21 fits into 117 5 times, leaving a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 1855.0
If we take 105 away from 117, we end up with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 21

Let's proceed to step 6:
21 goes into 121 5 times with a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 18555.0
Subtract 105 from 121 to get 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 21

Step 7:
The number 21 fits into 163 7 times, leaving a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 185557.0
Subtract 147 from 163 to get 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 21

Going ahead to step 8:
If we divide 162 by 21, we get 7 and a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 1855577.0
Subtracting 147 from 162 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
150 divided by 21 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 1855577.7
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1855577.71
The remainder is 9 after subtracting 21 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 11:
If we divide 90 by 21, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 1855577.714
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
60 divided by 21 is 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 1855577.7142
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
If we divide 180 by 21, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 1855577.71428
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
When dividing 120 by 21, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1855577.714285
Deduct 105 from 120 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 15:
If we divide 150 by 21, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 1855577.7142857
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 16:
If we divide 30 by 21, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1855577.71428571
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 1855577.71428571 with a balance of 9e-09.
