We're dividing 30123923 by 149 
We want to figure out the number of times 30123923 can be divided by 149.

Step 1:
149 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 149

Moving on to step 2:
The number 149 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 149

Step 3:
149 can be fit into 301 2 times, resulting in a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 298 from 301 and we're left with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 149

On to step 4:
149 goes into 32 0 times with a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we take 0 away from 32, we end up with 32.
Bring next digit (3) of the dividend behind the 32 and repeat the process: 323 / 149

Let's proceed to step 5:
The number 149 fits into 323 2 times, leaving a remainder of 25.
The next digit of our result is 2. 
Result so far: 202.0
Subtract 298 from 323 to get 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 149

Moving on to step 6:
149 can be fit into 259 1 times, resulting in a remainder of 110.
The number 1 becomes the next digit in our result. 
Result so far: 2021.0
If we subtract 149 from 259, we get 110.
Include the next digit (2) from the dividend after 110, then repeat: 1102 / 149

Going ahead to step 7:
When dividing 1102 by 149, we get 7 with a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 20217.0
The remainder is 59 after subtracting 1043 from 1102.
Grab the next digit (3) from the dividend, add it to 59, then carry on: 593 / 149

Step 8:
593 divided by 149 is 3 with a remainder of 146.
Write down 3 as next digit of the result. 
Result so far: 202173.0
Subtract 447 from 593 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 9:
If we divide 1460 by 149, we get 9 and a remainder of 119.
Put 9 as the next digit of the answer. 
Result so far: 202173.9
The remainder is 119 after subtracting 1341 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 10:
If we divide 1190 by 149, we get 7 and a remainder of 147.
Put 7 as the next digit of the answer. 
Result so far: 202173.97
Subtracting 1043 from 1190 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Let's proceed to step 11:
149 goes into 1470 9 times with a remainder of 129.
Put 9 as the next digit of the answer. 
Result so far: 202173.979
If we subtract 1341 from 1470, we get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 12:
When dividing 1290 by 149, we get 8 with a remainder of 98.
The next digit of our result is 8. 
Result so far: 202173.9798
The remainder is 98 after subtracting 1192 from 1290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 13:
If we divide 980 by 149, we get 6 and a remainder of 86.
The next digit of our result is 6. 
Result so far: 202173.97986
Subtract 894 from 980 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 14:
149 goes into 860 5 times with a remainder of 115.
The next digit of our result is 5. 
Result so far: 202173.979865
Subtract 745 from 860 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 15:
The number 149 fits into 1150 7 times, leaving a remainder of 107.
Record the quotient 7 as the next digit in the result. 
Result so far: 202173.9798657
Subtracting 1043 from 1150 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Advancing to step 16:
When dividing 1070 by 149, we get 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 202173.97986577
If we subtract 1043 from 1070, 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.

Our division results in 202173.97986577 with a remaining 2.7e-08.
