We look at the division of 945496 by 21 
We want to divide 945496 by 21.

Step 1:
The number 21 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 21

Let's proceed to step 2:
21 goes into 94 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 84 from 94, we get 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 21

Moving on to step 3:
21 can be fit into 105 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtracting 105 from 105 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 21

Step 4:
21 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 450.0
Subtract 0 from 4 to get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 21

On to step 5:
The number 21 fits into 49 2 times, leaving a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 4502.0
Subtract 42 from 49 to get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 21

Advancing to step 6:
21 can be fit into 76 3 times, resulting in a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 45023.0
Subtracting 63 from 76 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.

Moving on to step 7:
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: 45023.6
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.

Advancing to step 8:
21 goes into 40 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 45023.61
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 9:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 45023.619
Deduct 189 from 190 and we're left 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.

Going ahead to step 10:
10 divided by 21 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 45023.619
If we subtract 0 from 10, we 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 11:
21 goes into 100 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 45023.61904
If we take 84 away from 100, we end up 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.

Advancing to step 12:
21 goes into 160 7 times with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 45023.619047
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.

On to step 13:
130 divided by 21 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 45023.6190476
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.

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: 45023.61904761
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.

The final outcome is 45023.61904761, with a leftover of 1.9e-08.
