21889777 ÷ 102 
We're looking to find how many times 102 goes into 21889777.

On to step 1:
If we divide 2 by 102, we get 0 and 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 / 102

On to step 2:
102 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 102

On to step 3:
102 goes into 218 2 times with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 204 from 218 leaves us with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 102

Step 4:
102 goes into 148 1 times with a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 102 away from 148, we end up with 46.
Append the next digit (9) from the dividend to 46 and continue with: 469 / 102

Moving on to step 5:
If we divide 469 by 102, we get 4 and a remainder of 61.
Write down 4 as next digit of the result. 
Result so far: 214.0
Subtracting 408 from 469 leaves us with 61.
Grab the next digit (7) from the dividend, add it to 61, then carry on: 617 / 102

Moving on to step 6:
102 can be fit into 617 6 times, resulting in a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 2146.0
The remainder is 5 after subtracting 612 from 617.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 102

On to step 7:
If we divide 57 by 102, we get 0 and a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 21460.0
If we subtract 0 from 57, we get 57.
Include the next digit (7) from the dividend after 57, then repeat: 577 / 102

On to step 8:
577 divided by 102 is 5 with a remainder of 67.
Put 5 as the next digit of the answer. 
Result so far: 214605.0
Subtracting 510 from 577 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 9:
If we divide 670 by 102, we get 6 and a remainder of 58.
Put 6 as the next digit of the answer. 
Result so far: 214605.6
Deduct 612 from 670 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
102 goes into 580 5 times with a remainder of 70.
The next digit of our result is 5. 
Result so far: 214605.65
The remainder is 70 after subtracting 510 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
The number 102 fits into 700 6 times, leaving a remainder of 88.
Put 6 as the next digit of the answer. 
Result so far: 214605.656
Subtract 612 from 700 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 12:
The number 102 fits into 880 8 times, leaving a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 214605.6568
Subtracting 816 from 880 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
When dividing 640 by 102, we get 6 with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 214605.65686
If we subtract 612 from 640, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
280 divided by 102 is 2 with a remainder of 76.
The next digit of our result is 2. 
Result so far: 214605.656862
Subtracting 204 from 280 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 15:
If we divide 760 by 102, we get 7 and a remainder of 46.
Use 7 as the next digit of our solution. 
Result so far: 214605.6568627
If we take 714 away from 760, 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.

Step 16:
If we divide 460 by 102, we get 4 and a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 214605.65686274
Deduct 408 from 460 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 214605.65686274, and the remainder is 5.2e-08.
