151971 divided by 30 
Let's see how many times 30 fits into 151971.

Let's proceed to step 1:
When dividing 1 by 30, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 30

Moving on to step 2:
30 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 30

Advancing to step 3:
If we divide 151 by 30, we get 5 and a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 150 from 151 leaves us with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 30

Let's proceed to step 4:
When dividing 19 by 30, we get 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
The remainder is 19 after subtracting 0 from 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 30

Let's proceed to step 5:
When dividing 197 by 30, we get 6 with a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 506.0
The remainder is 17 after subtracting 180 from 197.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 30

Step 6:
If we divide 171 by 30, we get 5 and a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 5065.0
Subtract 150 from 171 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
If we divide 210 by 30, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 5065.7
If we subtract 210 from 210, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
When dividing 0 by 30, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5065.7
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5065.7
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 5065.7 and a remainder of 0.0.
