We're dividing 21078 by 46 
We want to divide 21078 by 46.

Moving on to step 1:
The number 46 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 46

Step 2:
If we divide 21 by 46, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 46

Step 3:
When dividing 210 by 46, we get 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 184 from 210, we get 26.
Take the next digit (7) from the dividend and append it to 26, then repeat: 267 / 46

Step 4:
46 goes into 267 5 times with a remainder of 37.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
If we subtract 230 from 267, we get 37.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 46

Let's proceed to step 5:
46 can be fit into 378 8 times, resulting in a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 458.0
Deduct 368 from 378 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 6:
The number 46 fits into 100 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 458.2
If we take 92 away from 100, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
The number 46 fits into 80 1 times, leaving a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 458.21
If we subtract 46 from 80, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
340 divided by 46 is 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 458.217
The remainder is 18 after subtracting 322 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
180 divided by 46 is 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 458.2173
Deduct 138 from 180 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 10:
When dividing 420 by 46, we get 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 458.21739
Deduct 414 from 420 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 11:
46 can be fit into 60 1 times, resulting in a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 458.217391
Subtract 46 from 60 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 12:
When dividing 140 by 46, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 458.2173913
If we take 138 away from 140, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
The number 46 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 458.2173913
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 458.2173913 with a balance of 2e-08.
