21806910 ÷ 945 
Our goal is to divide 21806910 by 945.

On to step 1:
2 divided by 945 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 945

Advancing to step 2:
945 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 945

Let's proceed to step 3:
When dividing 218 by 945, we get 0 with a remainder of 218.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 218, we end up with 218.
Append the next digit (0) from the dividend to 218 and continue with: 2180 / 945

On to step 4:
When dividing 2180 by 945, we get 2 with a remainder of 290.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1890 from 2180 and we're left with 290.
Grab the next digit (6) from the dividend, add it to 290, then carry on: 2906 / 945

Going ahead to step 5:
When dividing 2906 by 945, we get 3 with a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
The remainder is 71 after subtracting 2835 from 2906.
Take the next digit (9) from the dividend and append it to 71, then repeat: 719 / 945

Moving on to step 6:
945 goes into 719 0 times with a remainder of 719.
Write down 0 as next digit of the result. 
Result so far: 230.0
If we subtract 0 from 719, we get 719.
Bring next digit (1) of the dividend behind the 719 and repeat the process: 7191 / 945

Advancing to step 7:
If we divide 7191 by 945, we get 7 and a remainder of 576.
The next digit of our result is 7. 
Result so far: 2307.0
If we take 6615 away from 7191, we end up with 576.
Take the next digit (0) from the dividend and append it to 576, then repeat: 5760 / 945

Going ahead to step 8:
The number 945 fits into 5760 6 times, leaving a remainder of 90.
Use 6 as the next digit of our solution. 
Result so far: 23076.0
If we subtract 5670 from 5760, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 9:
The number 945 fits into 900 0 times, leaving a remainder of 900.
Record the quotient 0 as the next digit in the result. 
Result so far: 23076.0
Subtracting 0 from 900 leaves us with 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Step 10:
945 goes into 9000 9 times with a remainder of 495.
Use 9 as the next digit of our solution. 
Result so far: 23076.09
Deduct 8505 from 9000 and we're left with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Going ahead to step 11:
4950 divided by 945 is 5 with a remainder of 225.
Put 5 as the next digit of the answer. 
Result so far: 23076.095
If we take 4725 away from 4950, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 12:
When dividing 2250 by 945, we get 2 with a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 23076.0952
Subtract 1890 from 2250 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 13:
945 can be fit into 3600 3 times, resulting in a remainder of 765.
Put 3 as the next digit of the answer. 
Result so far: 23076.09523
Subtract 2835 from 3600 to get 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Let's proceed to step 14:
945 can be fit into 7650 8 times, resulting in a remainder of 90.
Record the quotient 8 as the next digit in the result. 
Result so far: 23076.095238
Subtract 7560 from 7650 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 15:
945 goes into 900 0 times with a remainder of 900.
The number 0 becomes the next digit in our result. 
Result so far: 23076.095238
Subtract 0 from 900 to get 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

On to step 16:
945 goes into 9000 9 times with a remainder of 495.
Use 9 as the next digit of our solution. 
Result so far: 23076.09523809
If we subtract 8505 from 9000, we get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

In conclusion, the division gives 23076.09523809 with a balance of 4.95e-07.
