We're dividing 943849 by 21 
We're looking to find how many times 21 goes into 943849.

Let's proceed to step 1:
21 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 21

Advancing to step 2:
94 divided by 21 is 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 84 away from 94, we end up with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 21

Advancing to step 3:
21 goes into 103 4 times with a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we take 84 away from 103, we end up with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 21

On to step 4:
21 can be fit into 198 9 times, resulting in a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 449.0
The remainder is 9 after subtracting 189 from 198.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 21

Going ahead to step 5:
The number 21 fits into 94 4 times, leaving a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 4494.0
Subtracting 84 from 94 leaves us with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 21

Going ahead to step 6:
If we divide 109 by 21, we get 5 and a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 44945.0
Subtract 105 from 109 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.

Let's proceed to step 7:
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: 44945.1
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.

Let's proceed to step 8:
190 divided by 21 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 44945.19
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.

Moving on to step 9:
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: 44945.19
Deduct 0 from 10 and we're left 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.

Moving on to step 10:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 44945.1904
If we subtract 84 from 100, 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.

Let's proceed to step 11:
When dividing 160 by 21, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 44945.19047
Subtracting 147 from 160 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 12:
If we divide 130 by 21, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 44945.190476
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 44945.1904761
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.

On to step 14:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 44945.19047619
If we take 189 away from 190, we end up 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.

The final result is 44945.19047619 with a remainder of 1e-09.
