We're dividing 21028830 by 69 
Let's see how many times 69 fits into 21028830.

On to step 1:
The number 69 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 69

Step 2:
69 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 69

Let's proceed to step 3:
If we divide 210 by 69, we get 3 and a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 207 from 210 to get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 69

Moving on to step 4:
69 can be fit into 32 0 times, resulting in a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we subtract 0 from 32, we get 32.
Take the next digit (8) from the dividend and append it to 32, then repeat: 328 / 69

Moving on to step 5:
69 goes into 328 4 times with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 304.0
If we take 276 away from 328, we end up with 52.
Append the next digit (8) from the dividend to 52 and continue with: 528 / 69

Going ahead to step 6:
528 divided by 69 is 7 with a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 3047.0
The remainder is 45 after subtracting 483 from 528.
Include the next digit (3) from the dividend after 45, then repeat: 453 / 69

Advancing to step 7:
69 can be fit into 453 6 times, resulting in a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 30476.0
If we subtract 414 from 453, we get 39.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 69

Advancing to step 8:
If we divide 390 by 69, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 304765.0
If we take 345 away from 390, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
69 goes into 450 6 times with a remainder of 36.
The next digit of our result is 6. 
Result so far: 304765.6
If we take 414 away from 450, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
69 goes into 360 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 304765.65
Deduct 345 from 360 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
The number 69 fits into 150 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 304765.652
The remainder is 12 after subtracting 138 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
69 can be fit into 120 1 times, resulting in a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 304765.6521
Subtracting 69 from 120 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 13:
When dividing 510 by 69, we get 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 304765.65217
Subtract 483 from 510 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 14:
When dividing 270 by 69, we get 3 with a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 304765.652173
The remainder is 63 after subtracting 207 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 15:
69 goes into 630 9 times with a remainder of 9.
The next digit of our result is 9. 
Result so far: 304765.6521739
If we take 621 away from 630, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 16:
When dividing 90 by 69, we get 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 304765.65217391
Subtracting 69 from 90 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

In conclusion, the division gives 304765.65217391 with a balance of 2.1e-08.
