848376 divided by 21 
We're looking to find how many times 21 goes into 848376.

Let's proceed to step 1:
21 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 21

Step 2:
21 can be fit into 84 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 0 after subtracting 84 from 84.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 21

Advancing to step 3:
When dividing 8 by 21, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we take 0 away from 8, we end up with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 21

On to step 4:
83 divided by 21 is 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 403.0
Subtracting 63 from 83 leaves us with 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 21

Let's proceed to step 5:
21 can be fit into 207 9 times, resulting in a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 4039.0
If we subtract 189 from 207, we get 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 21

Advancing to step 6:
21 goes into 186 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 40398.0
Deduct 168 from 186 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.

Let's proceed to step 7:
21 can be fit into 180 8 times, resulting in a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 40398.8
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
If we divide 120 by 21, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 40398.85
The remainder is 15 after subtracting 105 from 120.
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 9:
The number 21 fits into 150 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 40398.857
The remainder is 3 after subtracting 147 from 150.
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 10:
30 divided by 21 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 40398.8571
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.

Step 11:
21 goes into 90 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 40398.85714
Deduct 84 from 90 and we're left 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.

Going ahead to step 12:
The number 21 fits into 60 2 times, leaving a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 40398.857142
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
21 can be fit into 180 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 40398.8571428
Deduct 168 from 180 and we're left 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.

Advancing to step 14:
21 goes into 120 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 40398.85714285
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 40398.85714285 with a remaining 1.5e-08.
