We're dividing 142106 by 21 
We want to divide 142106 by 21.

Going ahead to step 1:
If we divide 1 by 21, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 21

Moving on to step 2:
The number 21 fits into 14 0 times, leaving a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 21

Step 3:
The number 21 fits into 142 6 times, leaving a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 126 from 142 leaves us with 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 21

Going ahead to step 4:
The number 21 fits into 161 7 times, leaving a remainder of 14.
The next digit of our result is 7. 
Result so far: 67.0
If we subtract 147 from 161, we get 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 21

Step 5:
21 goes into 140 6 times with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 676.0
The remainder is 14 after subtracting 126 from 140.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 21

Going ahead to step 6:
21 goes into 146 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 6766.0
If we take 126 away from 146, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 6766.9
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
110 divided by 21 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 6766.95
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 6766.952
If we take 42 away from 50, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
21 goes into 80 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 6766.9523
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 11:
21 goes into 170 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 6766.95238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
When dividing 20 by 21, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 6766.95238
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
200 divided by 21 is 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 6766.9523809
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 14:
110 divided by 21 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 6766.95238095
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 6766.95238095 with a balance of 5e-09.
