21771784 ÷ 801 
We want to figure out the number of times 21771784 can be divided by 801.

Moving on to step 1:
801 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
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 801

Advancing to step 2:
When dividing 21 by 801, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 801

On to step 3:
801 goes into 217 0 times with a remainder of 217.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 217 to get 217.
Append the next digit (7) from the dividend to 217 and continue with: 2177 / 801

Advancing to step 4:
When dividing 2177 by 801, we get 2 with a remainder of 575.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1602 from 2177 and we're left with 575.
Take the next digit (1) from the dividend and append it to 575, then repeat: 5751 / 801

On to step 5:
The number 801 fits into 5751 7 times, leaving a remainder of 144.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtracting 5607 from 5751 leaves us with 144.
Fetch the next digit (7) from the dividend, attach it to 144 and continue: 1447 / 801

Step 6:
801 can be fit into 1447 1 times, resulting in a remainder of 646.
Write down 1 as next digit of the result. 
Result so far: 271.0
Subtracting 801 from 1447 leaves us with 646.
Bring next digit (8) of the dividend behind the 646 and repeat the process: 6468 / 801

On to step 7:
When dividing 6468 by 801, we get 8 with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 2718.0
If we take 6408 away from 6468, we end up with 60.
Grab the next digit (4) from the dividend, add it to 60, then carry on: 604 / 801

Let's proceed to step 8:
If we divide 604 by 801, we get 0 and a remainder of 604.
Use 0 as the next digit of our solution. 
Result so far: 27180.0
Subtract 0 from 604 to get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Let's proceed to step 9:
801 goes into 6040 7 times with a remainder of 433.
The next digit of our result is 7. 
Result so far: 27180.7
Subtracting 5607 from 6040 leaves us with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Moving on to step 10:
If we divide 4330 by 801, we get 5 and a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 27180.75
Subtract 4005 from 4330 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 11:
801 can be fit into 3250 4 times, resulting in a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 27180.754
If we take 3204 away from 3250, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
When dividing 460 by 801, we get 0 with a remainder of 460.
Record the quotient 0 as the next digit in the result. 
Result so far: 27180.754
Subtract 0 from 460 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 13:
If we divide 4600 by 801, we get 5 and a remainder of 595.
The next digit of our result is 5. 
Result so far: 27180.75405
Subtracting 4005 from 4600 leaves us with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

On to step 14:
When dividing 5950 by 801, we get 7 with a remainder of 343.
Write down 7 as next digit of the result. 
Result so far: 27180.754057
The remainder is 343 after subtracting 5607 from 5950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Going ahead to step 15:
The number 801 fits into 3430 4 times, leaving a remainder of 226.
Use 4 as the next digit of our solution. 
Result so far: 27180.7540574
Subtracting 3204 from 3430 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 16:
If we divide 2260 by 801, we get 2 and a remainder of 658.
Record the quotient 2 as the next digit in the result. 
Result so far: 27180.75405742
The remainder is 658 after subtracting 1602 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

In conclusion, the division gives 27180.75405742 with a balance of 6.58e-07.
