346765 divided by 21 
Let's see how many times 21 fits into 346765.

Let's proceed to step 1:
If we divide 3 by 21, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 21

Going ahead to step 2:
If we divide 34 by 21, we get 1 and 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.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 21

On to step 3:
If we divide 136 by 21, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 126 from 136 and we're left with 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 21

Going ahead to step 4:
21 goes into 107 5 times with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 165.0
If we take 105 away from 107, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 21

Moving on to step 5:
When dividing 26 by 21, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1651.0
Deduct 21 from 26 and we're left with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 21

Moving on to step 6:
21 goes into 55 2 times with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 16512.0
Subtracting 42 from 55 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.

Step 7:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 16512.6
Subtract 126 from 130 to 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.

On to step 8:
If we divide 40 by 21, we get 1 and a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 16512.61
If we take 21 away from 40, we end up 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.

Let's proceed to step 9:
When dividing 190 by 21, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 16512.619
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.

Step 10:
If we divide 10 by 21, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 16512.619
If we take 0 away from 10, we end up with 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 11:
If we divide 100 by 21, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 16512.61904
Deduct 84 from 100 and we're left 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 12:
160 divided by 21 is 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 16512.619047
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.

Step 13:
130 divided by 21 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 16512.6190476
Subtract 126 from 130 to 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.

Step 14:
40 divided by 21 is 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 16512.61904761
If we take 21 away from 40, we end up 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.

In conclusion, the division gives 16512.61904761 with a balance of 1.9e-08.
