We're dividing 30602970 by 155 
We want to divide 30602970 by 155.

On to step 1:
155 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 155

On to step 2:
155 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 155

Moving on to step 3:
The number 155 fits into 306 1 times, leaving a remainder of 151.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 155 from 306 to get 151.
Append the next digit (0) from the dividend to 151 and continue with: 1510 / 155

Step 4:
155 goes into 1510 9 times with a remainder of 115.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 1395 from 1510 leaves us with 115.
Include the next digit (2) from the dividend after 115, then repeat: 1152 / 155

Moving on to step 5:
155 can be fit into 1152 7 times, resulting in a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 197.0
If we take 1085 away from 1152, we end up with 67.
Bring next digit (9) of the dividend behind the 67 and repeat the process: 679 / 155

Advancing to step 6:
If we divide 679 by 155, we get 4 and a remainder of 59.
The number 4 becomes the next digit in our result. 
Result so far: 1974.0
If we subtract 620 from 679, we get 59.
Include the next digit (7) from the dividend after 59, then repeat: 597 / 155

Advancing to step 7:
155 goes into 597 3 times with a remainder of 132.
Use 3 as the next digit of our solution. 
Result so far: 19743.0
If we take 465 away from 597, we end up with 132.
Include the next digit (0) from the dividend after 132, then repeat: 1320 / 155

On to step 8:
1320 divided by 155 is 8 with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 197438.0
If we take 1240 away from 1320, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
The number 155 fits into 800 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 197438.5
If we subtract 775 from 800, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
If we divide 250 by 155, we get 1 and a remainder of 95.
Use 1 as the next digit of our solution. 
Result so far: 197438.51
Deduct 155 from 250 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 11:
155 goes into 950 6 times with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 197438.516
Subtract 930 from 950 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
When dividing 200 by 155, we get 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 197438.5161
If we take 155 away from 200, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 13:
If we divide 450 by 155, we get 2 and a remainder of 140.
Put 2 as the next digit of the answer. 
Result so far: 197438.51612
If we subtract 310 from 450, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 14:
155 can be fit into 1400 9 times, resulting in a remainder of 5.
The next digit of our result is 9. 
Result so far: 197438.516129
Deduct 1395 from 1400 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 15:
If we divide 50 by 155, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 197438.516129
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 16:
500 divided by 155 is 3 with a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 197438.51612903
The remainder is 35 after subtracting 465 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 197438.51612903 with a remainder of 3.5e-08.
