30170 ÷ 51 
Let's see how many times 51 fits into 30170.

Let's proceed to step 1:
3 divided by 51 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 51

Let's proceed to step 2:
The number 51 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 51

Advancing to step 3:
51 goes into 301 5 times with a remainder of 46.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 255 away from 301, we end up with 46.
Bring next digit (7) of the dividend behind the 46 and repeat the process: 467 / 51

Going ahead to step 4:
467 divided by 51 is 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
If we take 459 away from 467, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 51

On to step 5:
51 goes into 80 1 times with a remainder of 29.
The next digit of our result is 1. 
Result so far: 591.0
Deduct 51 from 80 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 6:
51 goes into 290 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 591.5
If we take 255 away from 290, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
When dividing 350 by 51, we get 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 591.56
If we take 306 away from 350, we end up 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.

Step 8:
The number 51 fits into 440 8 times, leaving a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 591.568
Deduct 408 from 440 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
320 divided by 51 is 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 591.5686
Deduct 306 from 320 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
51 goes into 140 2 times with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 591.56862
If we take 102 away from 140, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
380 divided by 51 is 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 591.568627
If we subtract 357 from 380, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 12:
When dividing 230 by 51, we get 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 591.5686274
If we subtract 204 from 230, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
260 divided by 51 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 591.56862745
If we subtract 255 from 260, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 591.56862745, and the remainder is 5e-09.
