342694 ÷ 21 
Let's see how many times 21 fits into 342694.

Moving on to step 1:
3 divided by 21 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 21

Let's proceed to step 2:
34 divided by 21 is 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 21 from 34, we get 13.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 21

Going ahead to step 3:
The number 21 fits into 132 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 6 after subtracting 126 from 132.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 21

Let's proceed to step 4:
The number 21 fits into 66 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 163.0
If we take 63 away from 66, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 21

Advancing to step 5:
The number 21 fits into 39 1 times, leaving a remainder of 18.
The next digit of our result is 1. 
Result so far: 1631.0
Subtract 21 from 39 to get 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 21

Let's proceed to step 6:
When dividing 184 by 21, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 16318.0
The remainder is 16 after subtracting 168 from 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
21 can be fit into 160 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 16318.7
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 8:
130 divided by 21 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 16318.76
Subtracting 126 from 130 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 9:
When dividing 40 by 21, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 16318.761
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 10:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 16318.7619
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
The number 21 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 16318.7619
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
If we divide 100 by 21, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 16318.761904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
The number 21 fits into 160 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 16318.7619047
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 14:
If we divide 130 by 21, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 16318.76190476
Deduct 126 from 130 and we're left 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.

The final outcome is 16318.76190476, with a leftover of 4e-09.
