We're dividing 21789940 by 101 
We want to divide 21789940 by 101.

Let's proceed to step 1:
101 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
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 101

On to step 2:
If we divide 21 by 101, we get 0 and a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 101

Let's proceed to step 3:
When dividing 217 by 101, we get 2 with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 202 from 217, we get 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 101

Let's proceed to step 4:
The number 101 fits into 158 1 times, leaving a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 101 from 158 and we're left with 57.
Bring next digit (9) of the dividend behind the 57 and repeat the process: 579 / 101

Step 5:
579 divided by 101 is 5 with a remainder of 74.
Use 5 as the next digit of our solution. 
Result so far: 215.0
If we take 505 away from 579, we end up with 74.
Append the next digit (9) from the dividend to 74 and continue with: 749 / 101

Advancing to step 6:
101 goes into 749 7 times with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 2157.0
If we take 707 away from 749, we end up with 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 101

Advancing to step 7:
424 divided by 101 is 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 21574.0
Subtract 404 from 424 to get 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 101

Let's proceed to step 8:
200 divided by 101 is 1 with a remainder of 99.
Write down 1 as next digit of the result. 
Result so far: 215741.0
Subtracting 101 from 200 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Step 9:
101 goes into 990 9 times with a remainder of 81.
The next digit of our result is 9. 
Result so far: 215741.9
If we subtract 909 from 990, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 10:
101 goes into 810 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 215741.98
Deduct 808 from 810 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
When dividing 20 by 101, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 215741.98
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
If we divide 200 by 101, we get 1 and a remainder of 99.
Put 1 as the next digit of the answer. 
Result so far: 215741.9801
The remainder is 99 after subtracting 101 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 13:
101 can be fit into 990 9 times, resulting in a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 215741.98019
Subtracting 909 from 990 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 14:
810 divided by 101 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 215741.980198
If we take 808 away from 810, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 15:
101 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 215741.980198
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 16:
101 goes into 200 1 times with a remainder of 99.
Write down 1 as next digit of the result. 
Result so far: 215741.98019801
If we take 101 away from 200, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

The final outcome is 215741.98019801, with a leftover of 9.9e-08.
