We're dividing 965406 by 21 
Our goal is to divide 965406 by 21.

Advancing to step 1:
9 divided by 21 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 21

Let's proceed to step 2:
The number 21 fits into 96 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 84 from 96 and we're left with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 21

Advancing to step 3:
125 divided by 21 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 45.0
The remainder is 20 after subtracting 105 from 125.
Grab the next digit (4) from the dividend, add it to 20, then carry on: 204 / 21

Going ahead to step 4:
When dividing 204 by 21, we get 9 with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 459.0
Deduct 189 from 204 and we're left with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 21

Let's proceed to step 5:
21 goes into 150 7 times with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 4597.0
If we subtract 147 from 150, we get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 21

Going ahead to step 6:
36 divided by 21 is 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 45971.0
If we take 21 away from 36, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
150 divided by 21 is 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 45971.7
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
21 can be fit into 30 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 45971.71
Deduct 21 from 30 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 45971.714
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
When dividing 60 by 21, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 45971.7142
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
21 goes into 180 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 45971.71428
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
21 can be fit into 120 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 45971.714285
If we take 105 away from 120, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 45971.7142857
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 14:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 45971.71428571
The remainder is 9 after subtracting 21 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 45971.71428571, with a leftover of 9e-09.
