918007 ÷ 21 
We want to divide 918007 by 21.

On to step 1:
When dividing 9 by 21, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 21

Going ahead to step 2:
When dividing 91 by 21, we get 4 with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 84 from 91 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 21

Let's proceed to step 3:
The number 21 fits into 78 3 times, leaving a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 43.0
Deduct 63 from 78 and we're left with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 21

Let's proceed to step 4:
When dividing 150 by 21, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 437.0
Subtract 147 from 150 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 21

Moving on to step 5:
21 goes into 30 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 4371.0
If we subtract 21 from 30, we get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 21

On to step 6:
The number 21 fits into 97 4 times, leaving a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 43714.0
If we subtract 84 from 97, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 43714.6
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.

Moving on to step 8:
If we divide 40 by 21, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 43714.61
Subtracting 21 from 40 leaves us with 19.
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 9:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 43714.619
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.

Moving on to step 10:
When dividing 10 by 21, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 43714.619
If we subtract 0 from 10, we get 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 11:
The number 21 fits into 100 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 43714.61904
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.

Moving on to step 12:
160 divided by 21 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 43714.619047
Deduct 147 from 160 and we're left 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 13:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 43714.6190476
If we take 126 away from 130, we end up 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.

On to step 14:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 43714.61904761
Subtracting 21 from 40 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

In conclusion, the division gives 43714.61904761 with a balance of 1.9e-08.
