We're dividing 21602555 by 149 
We're looking to find how many times 149 goes into 21602555.

Step 1:
The number 149 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 149

Let's proceed to step 2:
21 divided by 149 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 149

Advancing to step 3:
The number 149 fits into 216 1 times, leaving a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 149 from 216, we get 67.
Take the next digit (0) from the dividend and append it to 67, then repeat: 670 / 149

Advancing to step 4:
670 divided by 149 is 4 with a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 596 from 670 leaves us with 74.
Take the next digit (2) from the dividend and append it to 74, then repeat: 742 / 149

Let's proceed to step 5:
149 can be fit into 742 4 times, resulting in a remainder of 146.
Use 4 as the next digit of our solution. 
Result so far: 144.0
Subtract 596 from 742 to get 146.
Fetch the next digit (5) from the dividend, attach it to 146 and continue: 1465 / 149

Moving on to step 6:
149 can be fit into 1465 9 times, resulting in a remainder of 124.
Record the quotient 9 as the next digit in the result. 
Result so far: 1449.0
Subtracting 1341 from 1465 leaves us with 124.
Bring next digit (5) of the dividend behind the 124 and repeat the process: 1245 / 149

Moving on to step 7:
The number 149 fits into 1245 8 times, leaving a remainder of 53.
Put 8 as the next digit of the answer. 
Result so far: 14498.0
If we take 1192 away from 1245, we end up with 53.
Append the next digit (5) from the dividend to 53 and continue with: 535 / 149

Step 8:
When dividing 535 by 149, we get 3 with a remainder of 88.
Record the quotient 3 as the next digit in the result. 
Result so far: 144983.0
Subtract 447 from 535 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 9:
880 divided by 149 is 5 with a remainder of 135.
Use 5 as the next digit of our solution. 
Result so far: 144983.5
If we subtract 745 from 880, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 10:
1350 divided by 149 is 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 144983.59
If we take 1341 away from 1350, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
149 goes into 90 0 times with a remainder of 90.
The next digit of our result is 0. 
Result so far: 144983.59
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 12:
900 divided by 149 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 144983.5906
Deduct 894 from 900 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
149 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 144983.5906
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
The number 149 fits into 600 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 144983.590604
The remainder is 4 after subtracting 596 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 15:
40 divided by 149 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 144983.590604
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 16:
The number 149 fits into 400 2 times, leaving a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 144983.59060402
Subtract 298 from 400 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The quotient of the division is 144983.59060402, and the remainder is 1.02e-07.
