We're dividing 167218 by 21 
We're looking to find how many times 21 goes into 167218.

Going ahead to step 1:
21 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 21

Moving on to step 2:
16 divided by 21 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Grab the next digit (7) from the dividend, add it to 16, then carry on: 167 / 21

Step 3:
If we divide 167 by 21, we get 7 and a remainder of 20.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 147 from 167 and we're left with 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 21

On to step 4:
21 goes into 202 9 times with a remainder of 13.
The next digit of our result is 9. 
Result so far: 79.0
Deduct 189 from 202 and we're left with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 21

Moving on to step 5:
21 goes into 131 6 times with a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 796.0
Subtracting 126 from 131 leaves us with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 21

Step 6:
58 divided by 21 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 7962.0
If we subtract 42 from 58, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
160 divided by 21 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 7962.7
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 8:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 7962.76
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.

On to step 9:
If we divide 40 by 21, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 7962.761
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
When dividing 190 by 21, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 7962.7619
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
If we divide 10 by 21, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 7962.7619
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
When dividing 100 by 21, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 7962.761904
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
21 goes into 160 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 7962.7619047
If we take 147 away from 160, we end up 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.

Advancing to step 14:
21 can be fit into 130 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 7962.76190476
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 7962.76190476 with a balance of 4e-09.
