21085654 ÷ 529 
Our goal is to divide 21085654 by 529.

Going ahead to step 1:
529 can be fit into 2 0 times, resulting in 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.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 529

Step 2:
If we divide 21 by 529, we get 0 and 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 (0) from the dividend and append it to 21, then repeat: 210 / 529

Step 3:
If we divide 210 by 529, we get 0 and a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 210 to get 210.
Fetch the next digit (8) from the dividend, attach it to 210 and continue: 2108 / 529

On to step 4:
2108 divided by 529 is 3 with a remainder of 521.
The next digit of our result is 3. 
Result so far: 3.0
If we take 1587 away from 2108, we end up with 521.
Fetch the next digit (5) from the dividend, attach it to 521 and continue: 5215 / 529

Step 5:
5215 divided by 529 is 9 with a remainder of 454.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
The remainder is 454 after subtracting 4761 from 5215.
Include the next digit (6) from the dividend after 454, then repeat: 4546 / 529

Going ahead to step 6:
4546 divided by 529 is 8 with a remainder of 314.
Record the quotient 8 as the next digit in the result. 
Result so far: 398.0
Subtracting 4232 from 4546 leaves us with 314.
Grab the next digit (5) from the dividend, add it to 314, then carry on: 3145 / 529

Step 7:
When dividing 3145 by 529, we get 5 with a remainder of 500.
Use 5 as the next digit of our solution. 
Result so far: 3985.0
The remainder is 500 after subtracting 2645 from 3145.
Take the next digit (4) from the dividend and append it to 500, then repeat: 5004 / 529

Going ahead to step 8:
5004 divided by 529 is 9 with a remainder of 243.
The next digit of our result is 9. 
Result so far: 39859.0
Subtracting 4761 from 5004 leaves us with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Advancing to step 9:
2430 divided by 529 is 4 with a remainder of 314.
The number 4 becomes the next digit in our result. 
Result so far: 39859.4
Subtracting 2116 from 2430 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 10:
If we divide 3140 by 529, we get 5 and a remainder of 495.
Use 5 as the next digit of our solution. 
Result so far: 39859.45
Subtracting 2645 from 3140 leaves us 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.

Moving on to step 11:
529 goes into 4950 9 times with a remainder of 189.
Record the quotient 9 as the next digit in the result. 
Result so far: 39859.459
The remainder is 189 after subtracting 4761 from 4950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

On to step 12:
When dividing 1890 by 529, we get 3 with a remainder of 303.
Put 3 as the next digit of the answer. 
Result so far: 39859.4593
The remainder is 303 after subtracting 1587 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Let's proceed to step 13:
529 can be fit into 3030 5 times, resulting in a remainder of 385.
The number 5 becomes the next digit in our result. 
Result so far: 39859.45935
Subtract 2645 from 3030 to get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Moving on to step 14:
529 can be fit into 3850 7 times, resulting in a remainder of 147.
The number 7 becomes the next digit in our result. 
Result so far: 39859.459357
The remainder is 147 after subtracting 3703 from 3850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Going ahead to step 15:
The number 529 fits into 1470 2 times, leaving a remainder of 412.
The next digit of our result is 2. 
Result so far: 39859.4593572
The remainder is 412 after subtracting 1058 from 1470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Step 16:
If we divide 4120 by 529, we get 7 and a remainder of 417.
Write down 7 as next digit of the result. 
Result so far: 39859.45935727
If we take 3703 away from 4120, we end up with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

After the division, we end up with 39859.45935727 and a remainder of 4.17e-07.
