We divide 961888 by 21
Let's see how many times 21 fits into 961888.

Going ahead to step 1:
21 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us 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.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 12 after subtracting 84 from 96.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 21

Moving on to step 3:
The number 21 fits into 121 5 times, leaving a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we take 105 away from 121, we end up with 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 21

Going ahead to step 4:
If we divide 168 by 21, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 458.0
Deduct 168 from 168 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 21

Moving on to step 5:
If we divide 8 by 21, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 4580.0
If we take 0 away from 8, we end up with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 21

Let's proceed to step 6:
21 goes into 88 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 45804.0
Subtract 84 from 88 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.

Going ahead to step 7:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 45804.1
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.

Step 8:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 45804.19
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.

Moving on to step 9:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 45804.19
Subtracting 0 from 10 leaves us 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.

Advancing to step 10:
21 goes into 100 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 45804.1904
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.

Let's proceed to step 11:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 45804.19047
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 12:
When dividing 130 by 21, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 45804.190476
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.

Going ahead to step 13:
The number 21 fits into 40 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 45804.1904761
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 14:
190 divided by 21 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 45804.19047619
Subtract 189 from 190 to get 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 outcome is 45804.19047619, with a leftover of 1e-09.
