We divide 378655 by 21
Let's see how many times 21 fits into 378655.

Moving on to step 1:
21 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 21

Let's proceed to step 2:
The number 21 fits into 37 1 times, leaving a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 21 from 37 leaves us with 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 21

Advancing to step 3:
168 divided by 21 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 168 from 168 leaves us with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 21

Advancing to step 4:
6 divided by 21 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 180.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 21

Advancing to step 5:
21 goes into 65 3 times with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 1803.0
If we subtract 63 from 65, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 21

Moving on to step 6:
When dividing 25 by 21, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 18031.0
If we subtract 21 from 25, we 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.

Step 7:
If we divide 40 by 21, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 18031.1
The remainder is 19 after subtracting 21 from 40.
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 8:
When dividing 190 by 21, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 18031.19
Subtracting 189 from 190 leaves us 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.

Going ahead to step 9:
10 divided by 21 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 18031.19
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.

On to step 10:
If we divide 100 by 21, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 18031.1904
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.
Write down 7 as next digit of the result. 
Result so far: 18031.19047
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.

Let's proceed to step 12:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 18031.190476
If we subtract 126 from 130, we 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.

On 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: 18031.1904761
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.

Going ahead to step 14:
21 goes into 190 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 18031.19047619
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 quotient of the division is 18031.19047619, and the remainder is 1e-09.
