21777693 ÷ 86 
We're looking to find how many times 86 goes into 21777693.

Let's proceed to step 1:
If we divide 2 by 86, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
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 / 86

Going ahead to step 2:
86 goes into 21 0 times with 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.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 86

Advancing to step 3:
When dividing 217 by 86, we get 2 with a remainder of 45.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 172 from 217 to get 45.
Grab the next digit (7) from the dividend, add it to 45, then carry on: 457 / 86

Moving on to step 4:
457 divided by 86 is 5 with a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 25.0
The remainder is 27 after subtracting 430 from 457.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 86

Step 5:
277 divided by 86 is 3 with a remainder of 19.
The next digit of our result is 3. 
Result so far: 253.0
If we take 258 away from 277, we end up with 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 86

Going ahead to step 6:
196 divided by 86 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 2532.0
If we subtract 172 from 196, we get 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 86

Going ahead to step 7:
249 divided by 86 is 2 with a remainder of 77.
The number 2 becomes the next digit in our result. 
Result so far: 25322.0
If we take 172 away from 249, we end up with 77.
Take the next digit (3) from the dividend and append it to 77, then repeat: 773 / 86

Step 8:
773 divided by 86 is 8 with a remainder of 85.
The number 8 becomes the next digit in our result. 
Result so far: 253228.0
If we take 688 away from 773, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 9:
86 goes into 850 9 times with a remainder of 76.
Put 9 as the next digit of the answer. 
Result so far: 253228.9
Subtract 774 from 850 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 10:
86 can be fit into 760 8 times, resulting in a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 253228.98
If we take 688 away from 760, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 11:
720 divided by 86 is 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 253228.988
The remainder is 32 after subtracting 688 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 253228.988 with a remaining 0.0032.
