We divide 755386 by 21
We want to divide 755386 by 21.

Let's proceed to step 1:
21 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 21

On to step 2:
When dividing 75 by 21, we get 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 63 from 75, we get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 21

Going ahead to step 3:
21 can be fit into 125 5 times, resulting in a remainder of 20.
The next digit of our result is 5. 
Result so far: 35.0
If we take 105 away from 125, we end up with 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 21

On to step 4:
21 can be fit into 203 9 times, resulting in a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 359.0
If we subtract 189 from 203, we get 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 21

Let's proceed to step 5:
The number 21 fits into 148 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 3597.0
The remainder is 1 after subtracting 147 from 148.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 21

Let's proceed to step 6:
If we divide 16 by 21, we get 0 and a remainder of 16.
The next digit of our result is 0. 
Result so far: 35970.0
The remainder is 16 after subtracting 0 from 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
If we divide 160 by 21, we get 7 and a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 35970.7
Subtract 147 from 160 to 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.

Going ahead to step 8:
When dividing 130 by 21, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 35970.76
If we take 126 away from 130, we end up 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.

Going ahead to step 9:
21 goes into 40 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 35970.761
If we subtract 21 from 40, we 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.

Step 10:
21 goes into 190 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 35970.7619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
10 divided by 21 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 35970.7619
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.

Let's proceed to step 12:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 35970.761904
Subtract 84 from 100 to 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.

Advancing to step 13:
21 goes into 160 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 35970.7619047
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.

Advancing to step 14:
21 goes into 130 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 35970.76190476
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.

Our division results in 35970.76190476 with a remaining 4e-09.
