21267766 ÷ 528 
We want to divide 21267766 by 528.

Moving on to step 1:
528 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 528

Step 2:
When dividing 21 by 528, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 528

Going ahead to step 3:
When dividing 212 by 528, we get 0 with a remainder of 212.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 212, we end up with 212.
Fetch the next digit (6) from the dividend, attach it to 212 and continue: 2126 / 528

On to step 4:
When dividing 2126 by 528, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 2112 from 2126 and we're left with 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 528

Let's proceed to step 5:
When dividing 147 by 528, we get 0 with a remainder of 147.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Deduct 0 from 147 and we're left with 147.
Bring next digit (7) of the dividend behind the 147 and repeat the process: 1477 / 528

Advancing to step 6:
If we divide 1477 by 528, we get 2 and a remainder of 421.
Write down 2 as next digit of the result. 
Result so far: 402.0
The remainder is 421 after subtracting 1056 from 1477.
Include the next digit (6) from the dividend after 421, then repeat: 4216 / 528

Step 7:
528 can be fit into 4216 7 times, resulting in a remainder of 520.
Write down 7 as next digit of the result. 
Result so far: 4027.0
Deduct 3696 from 4216 and we're left with 520.
Fetch the next digit (6) from the dividend, attach it to 520 and continue: 5206 / 528

Advancing to step 8:
When dividing 5206 by 528, we get 9 with a remainder of 454.
The number 9 becomes the next digit in our result. 
Result so far: 40279.0
Subtract 4752 from 5206 to get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Let's proceed to step 9:
4540 divided by 528 is 8 with a remainder of 316.
The number 8 becomes the next digit in our result. 
Result so far: 40279.8
If we take 4224 away from 4540, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 10:
528 can be fit into 3160 5 times, resulting in a remainder of 520.
Record the quotient 5 as the next digit in the result. 
Result so far: 40279.85
Deduct 2640 from 3160 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 11:
5200 divided by 528 is 9 with a remainder of 448.
Use 9 as the next digit of our solution. 
Result so far: 40279.859
Subtracting 4752 from 5200 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Let's proceed to step 12:
528 goes into 4480 8 times with a remainder of 256.
Put 8 as the next digit of the answer. 
Result so far: 40279.8598
Deduct 4224 from 4480 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 13:
2560 divided by 528 is 4 with a remainder of 448.
The next digit of our result is 4. 
Result so far: 40279.85984
Deduct 2112 from 2560 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 14:
The number 528 fits into 4480 8 times, leaving a remainder of 256.
Put 8 as the next digit of the answer. 
Result so far: 40279.859848
The remainder is 256 after subtracting 4224 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 15:
The number 528 fits into 2560 4 times, leaving a remainder of 448.
Use 4 as the next digit of our solution. 
Result so far: 40279.8598484
The remainder is 448 after subtracting 2112 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 16:
When dividing 4480 by 528, we get 8 with a remainder of 256.
Record the quotient 8 as the next digit in the result. 
Result so far: 40279.85984848
Subtracting 4224 from 4480 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final outcome is 40279.85984848, with a leftover of 2.56e-07.
