We're dividing 21942566 by 149 
We want to figure out the number of times 21942566 can be divided by 149.

Step 1:
When dividing 2 by 149, we get 0 with 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.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 149

On to step 2:
If we divide 21 by 149, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 149

Going ahead to step 3:
If we divide 219 by 149, we get 1 and a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 149 from 219 leaves us with 70.
Bring next digit (4) of the dividend behind the 70 and repeat the process: 704 / 149

Let's proceed to step 4:
149 goes into 704 4 times with a remainder of 108.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 596 from 704 leaves us with 108.
Grab the next digit (2) from the dividend, add it to 108, then carry on: 1082 / 149

Let's proceed to step 5:
If we divide 1082 by 149, we get 7 and a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 147.0
The remainder is 39 after subtracting 1043 from 1082.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 149

Going ahead to step 6:
395 divided by 149 is 2 with a remainder of 97.
Put 2 as the next digit of the answer. 
Result so far: 1472.0
If we subtract 298 from 395, we get 97.
Fetch the next digit (6) from the dividend, attach it to 97 and continue: 976 / 149

Moving on to step 7:
When dividing 976 by 149, we get 6 with a remainder of 82.
The number 6 becomes the next digit in our result. 
Result so far: 14726.0
Deduct 894 from 976 and we're left with 82.
Grab the next digit (6) from the dividend, add it to 82, then carry on: 826 / 149

Advancing to step 8:
826 divided by 149 is 5 with a remainder of 81.
Put 5 as the next digit of the answer. 
Result so far: 147265.0
If we subtract 745 from 826, 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 9:
810 divided by 149 is 5 with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 147265.5
If we subtract 745 from 810, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 10:
149 goes into 650 4 times with a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 147265.54
If we subtract 596 from 650, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 11:
If we divide 540 by 149, we get 3 and a remainder of 93.
The number 3 becomes the next digit in our result. 
Result so far: 147265.543
If we take 447 away from 540, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 12:
If we divide 930 by 149, we get 6 and a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 147265.5436
Subtracting 894 from 930 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 13:
149 goes into 360 2 times with a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 147265.54362
Subtract 298 from 360 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 14:
620 divided by 149 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 147265.543624
Subtracting 596 from 620 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 15:
The number 149 fits into 240 1 times, leaving a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 147265.5436241
If we take 149 away from 240, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 16:
The number 149 fits into 910 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 147265.54362416
Subtract 894 from 910 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 147265.54362416 with a remainder of 1.6e-08.
