85667143 divided by 30 
We want to divide 85667143 by 30.

On to step 1:
8 divided by 30 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 30

Let's proceed to step 2:
85 divided by 30 is 2 with a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 60 from 85, we get 25.
Fetch the next digit (6) from the dividend, attach it to 25 and continue: 256 / 30

Step 3:
The number 30 fits into 256 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we subtract 240 from 256, we get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 30

On to step 4:
If we divide 166 by 30, we get 5 and a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 285.0
Subtract 150 from 166 to get 16.
Include the next digit (7) from the dividend after 16, then repeat: 167 / 30

Going ahead to step 5:
When dividing 167 by 30, we get 5 with a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 2855.0
If we take 150 away from 167, we end up with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 30

Step 6:
171 divided by 30 is 5 with a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 28555.0
Deduct 150 from 171 and we're left with 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 30

Going ahead to step 7:
30 goes into 214 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 285557.0
Subtracting 210 from 214 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 30

Moving on to step 8:
When dividing 43 by 30, we get 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 2855571.0
The remainder is 13 after subtracting 30 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
130 divided by 30 is 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 2855571.4
Subtract 120 from 130 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
If we divide 100 by 30, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 2855571.43
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
If we divide 100 by 30, we get 3 and a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 2855571.433
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 2855571.433 with a remainder of 0.001.
