We divide 149889 by 642
We're looking to find how many times 642 goes into 149889.

Moving on to step 1:
The number 642 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 642

Step 2:
If we divide 14 by 642, we get 0 and a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 642

Advancing to step 3:
642 can be fit into 149 0 times, resulting in a remainder of 149.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 149, we end up with 149.
Bring next digit (8) of the dividend behind the 149 and repeat the process: 1498 / 642

Going ahead to step 4:
642 goes into 1498 2 times with a remainder of 214.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 214 after subtracting 1284 from 1498.
Grab the next digit (8) from the dividend, add it to 214, then carry on: 2148 / 642

Step 5:
642 can be fit into 2148 3 times, resulting in a remainder of 222.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 222 after subtracting 1926 from 2148.
Grab the next digit (9) from the dividend, add it to 222, then carry on: 2229 / 642

Let's proceed to step 6:
642 can be fit into 2229 3 times, resulting in a remainder of 303.
The next digit of our result is 3. 
Result so far: 233.0
If we subtract 1926 from 2229, we get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Advancing to step 7:
642 can be fit into 3030 4 times, resulting in a remainder of 462.
Use 4 as the next digit of our solution. 
Result so far: 233.4
Subtracting 2568 from 3030 leaves us with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Step 8:
If we divide 4620 by 642, we get 7 and a remainder of 126.
The number 7 becomes the next digit in our result. 
Result so far: 233.47
Subtract 4494 from 4620 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 9:
If we divide 1260 by 642, we get 1 and a remainder of 618.
The next digit of our result is 1. 
Result so far: 233.471
If we subtract 642 from 1260, we get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Step 10:
If we divide 6180 by 642, we get 9 and a remainder of 402.
Use 9 as the next digit of our solution. 
Result so far: 233.4719
The remainder is 402 after subtracting 5778 from 6180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Let's proceed to step 11:
642 goes into 4020 6 times with a remainder of 168.
The number 6 becomes the next digit in our result. 
Result so far: 233.47196
If we take 3852 away from 4020, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 12:
642 goes into 1680 2 times with a remainder of 396.
Record the quotient 2 as the next digit in the result. 
Result so far: 233.471962
If we subtract 1284 from 1680, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 13:
3960 divided by 642 is 6 with a remainder of 108.
The number 6 becomes the next digit in our result. 
Result so far: 233.4719626
If we subtract 3852 from 3960, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 14:
The number 642 fits into 1080 1 times, leaving a remainder of 438.
Write down 1 as next digit of the result. 
Result so far: 233.47196261
If we subtract 642 from 1080, we get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

In conclusion, the division gives 233.47196261 with a balance of 4.38e-07.
