We look at the division of 30156374 by 215 
Let's see how many times 215 fits into 30156374.

On to step 1:
If we divide 3 by 215, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 215

On to step 2:
When dividing 30 by 215, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 215

Advancing to step 3:
The number 215 fits into 301 1 times, leaving a remainder of 86.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 215 away from 301, we end up with 86.
Append the next digit (5) from the dividend to 86 and continue with: 865 / 215

Moving on to step 4:
865 divided by 215 is 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 860 from 865 to get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 215

On to step 5:
215 goes into 56 0 times with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
Deduct 0 from 56 and we're left with 56.
Append the next digit (3) from the dividend to 56 and continue with: 563 / 215

Going ahead to step 6:
The number 215 fits into 563 2 times, leaving a remainder of 133.
Use 2 as the next digit of our solution. 
Result so far: 1402.0
Subtracting 430 from 563 leaves us with 133.
Include the next digit (7) from the dividend after 133, then repeat: 1337 / 215

Let's proceed to step 7:
When dividing 1337 by 215, we get 6 with a remainder of 47.
The number 6 becomes the next digit in our result. 
Result so far: 14026.0
Subtracting 1290 from 1337 leaves us with 47.
Fetch the next digit (4) from the dividend, attach it to 47 and continue: 474 / 215

Advancing to step 8:
If we divide 474 by 215, we get 2 and a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 140262.0
Deduct 430 from 474 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
When dividing 440 by 215, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 140262.2
Subtracting 430 from 440 leaves us 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.

Moving on to step 10:
When dividing 100 by 215, we get 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 140262.2
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 11:
If we divide 1000 by 215, we get 4 and a remainder of 140.
Record the quotient 4 as the next digit in the result. 
Result so far: 140262.204
If we take 860 away from 1000, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 12:
1400 divided by 215 is 6 with a remainder of 110.
Write down 6 as next digit of the result. 
Result so far: 140262.2046
Deduct 1290 from 1400 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 13:
If we divide 1100 by 215, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 140262.20465
Subtract 1075 from 1100 to 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.

Step 14:
215 can be fit into 250 1 times, resulting in a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 140262.204651
The remainder is 35 after subtracting 215 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 15:
If we divide 350 by 215, we get 1 and a remainder of 135.
The number 1 becomes the next digit in our result. 
Result so far: 140262.2046511
Deduct 215 from 350 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Our division results in 140262.2046511 with a remaining 1.35e-06.
