21423748 ÷ 107 
Let's see how many times 107 fits into 21423748.

On to step 1:
If we divide 2 by 107, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 107

Moving on to step 2:
21 divided by 107 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 107

Step 3:
If we divide 214 by 107, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 0 after subtracting 214 from 214.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 107

Going ahead to step 4:
107 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 2, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 107

On to step 5:
23 divided by 107 is 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 200.0
If we take 0 away from 23, we end up with 23.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 107

Step 6:
107 goes into 237 2 times with a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 2002.0
Subtracting 214 from 237 leaves us with 23.
Take the next digit (4) from the dividend and append it to 23, then repeat: 234 / 107

Let's proceed to step 7:
107 goes into 234 2 times with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 20022.0
If we take 214 away from 234, we end up with 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 107

Let's proceed to step 8:
107 can be fit into 208 1 times, resulting in a remainder of 101.
Write down 1 as next digit of the result. 
Result so far: 200221.0
Subtract 107 from 208 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 9:
107 goes into 1010 9 times with a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 200221.9
The remainder is 47 after subtracting 963 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 10:
When dividing 470 by 107, we get 4 with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 200221.94
Subtracting 428 from 470 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
420 divided by 107 is 3 with a remainder of 99.
The number 3 becomes the next digit in our result. 
Result so far: 200221.943
Subtract 321 from 420 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 12:
The number 107 fits into 990 9 times, leaving a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 200221.9439
If we subtract 963 from 990, we 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.

On to step 13:
The number 107 fits into 270 2 times, leaving a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 200221.94392
If we subtract 214 from 270, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 14:
If we divide 560 by 107, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 200221.943925
Subtract 535 from 560 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 15:
250 divided by 107 is 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 200221.9439252
If we subtract 214 from 250, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 16:
If we divide 360 by 107, we get 3 and a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 200221.94392523
Subtract 321 from 360 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 200221.94392523, and the remainder is 3.9e-08.
