We're dividing 30258243 by 154 
Our goal is to divide 30258243 by 154.

Going ahead to step 1:
The number 154 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 154

Let's proceed to step 2:
30 divided by 154 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 154

On to step 3:
154 goes into 302 1 times with a remainder of 148.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 154 from 302 and we're left with 148.
Fetch the next digit (5) from the dividend, attach it to 148 and continue: 1485 / 154

Advancing to step 4:
The number 154 fits into 1485 9 times, leaving a remainder of 99.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 1386 from 1485 and we're left with 99.
Append the next digit (8) from the dividend to 99 and continue with: 998 / 154

Advancing to step 5:
154 goes into 998 6 times with a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 196.0
Subtracting 924 from 998 leaves us with 74.
Bring next digit (2) of the dividend behind the 74 and repeat the process: 742 / 154

Advancing to step 6:
154 can be fit into 742 4 times, resulting in a remainder of 126.
The number 4 becomes the next digit in our result. 
Result so far: 1964.0
Subtracting 616 from 742 leaves us with 126.
Grab the next digit (4) from the dividend, add it to 126, then carry on: 1264 / 154

Moving on to step 7:
The number 154 fits into 1264 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 19648.0
If we take 1232 away from 1264, we end up with 32.
Fetch the next digit (3) from the dividend, attach it to 32 and continue: 323 / 154

Moving on to step 8:
When dividing 323 by 154, we get 2 with a remainder of 15.
The next digit of our result is 2. 
Result so far: 196482.0
Subtract 308 from 323 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
150 divided by 154 is 0 with a remainder of 150.
The next digit of our result is 0. 
Result so far: 196482.0
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 10:
154 goes into 1500 9 times with a remainder of 114.
Put 9 as the next digit of the answer. 
Result so far: 196482.09
Subtracting 1386 from 1500 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 11:
The number 154 fits into 1140 7 times, leaving a remainder of 62.
Write down 7 as next digit of the result. 
Result so far: 196482.097
Deduct 1078 from 1140 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 12:
When dividing 620 by 154, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 196482.0974
Deduct 616 from 620 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
If we divide 40 by 154, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 196482.0974
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
154 goes into 400 2 times with a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 196482.097402
The remainder is 92 after subtracting 308 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 15:
154 can be fit into 920 5 times, resulting in a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 196482.0974025
The remainder is 150 after subtracting 770 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 16:
The number 154 fits into 1500 9 times, leaving a remainder of 114.
The number 9 becomes the next digit in our result. 
Result so far: 196482.09740259
Subtract 1386 from 1500 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

After the division, we end up with 196482.09740259 and a remainder of 1.14e-07.
