Let's divide 846898 by 21
We're looking to find how many times 21 goes into 846898.

Let's proceed to step 1:
When dividing 8 by 21, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 21

Advancing to step 2:
If we divide 84 by 21, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 84 from 84 to get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 21

Let's proceed to step 3:
The number 21 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we subtract 0 from 6, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 21

Advancing to step 4:
When dividing 68 by 21, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 403.0
If we subtract 63 from 68, we get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 21

Step 5:
The number 21 fits into 59 2 times, leaving a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 4032.0
If we subtract 42 from 59, we get 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 21

Moving on to step 6:
When dividing 178 by 21, we get 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 40328.0
Subtracting 168 from 178 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.

On to step 7:
If we divide 100 by 21, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 40328.4
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 8:
If we divide 160 by 21, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 40328.47
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.

Let's proceed to step 9:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 40328.476
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.

Let's proceed to step 10:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 40328.4761
Subtract 21 from 40 to 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.

Advancing to step 11:
190 divided by 21 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 40328.47619
If we subtract 189 from 190, we 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.

On to step 12:
If we divide 10 by 21, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 40328.47619
If we take 0 away from 10, we end up 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 13:
100 divided by 21 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 40328.4761904
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 14:
160 divided by 21 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 40328.47619047
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.

The final outcome is 40328.47619047, with a leftover of 1.3e-08.
