We look at the division of 30985901 by 252 
Let's see how many times 252 fits into 30985901.

Let's proceed to step 1:
If we divide 3 by 252, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 252

Let's proceed to step 2:
The number 252 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 252

Moving on to step 3:
When dividing 309 by 252, we get 1 with a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 252 from 309 to get 57.
Grab the next digit (8) from the dividend, add it to 57, then carry on: 578 / 252

Moving on to step 4:
578 divided by 252 is 2 with a remainder of 74.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 74 after subtracting 504 from 578.
Append the next digit (5) from the dividend to 74 and continue with: 745 / 252

Moving on to step 5:
If we divide 745 by 252, we get 2 and a remainder of 241.
Put 2 as the next digit of the answer. 
Result so far: 122.0
Subtract 504 from 745 to get 241.
Take the next digit (9) from the dividend and append it to 241, then repeat: 2419 / 252

Going ahead to step 6:
When dividing 2419 by 252, we get 9 with a remainder of 151.
The number 9 becomes the next digit in our result. 
Result so far: 1229.0
The remainder is 151 after subtracting 2268 from 2419.
Fetch the next digit (0) from the dividend, attach it to 151 and continue: 1510 / 252

Going ahead to step 7:
When dividing 1510 by 252, we get 5 with a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 12295.0
Subtracting 1260 from 1510 leaves us with 250.
Append the next digit (1) from the dividend to 250 and continue with: 2501 / 252

Moving on to step 8:
The number 252 fits into 2501 9 times, leaving a remainder of 233.
The next digit of our result is 9. 
Result so far: 122959.0
If we take 2268 away from 2501, we end up with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Going ahead to step 9:
252 can be fit into 2330 9 times, resulting in a remainder of 62.
Record the quotient 9 as the next digit in the result. 
Result so far: 122959.9
Subtracting 2268 from 2330 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 10:
When dividing 620 by 252, we get 2 with a remainder of 116.
Record the quotient 2 as the next digit in the result. 
Result so far: 122959.92
Subtract 504 from 620 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 11:
If we divide 1160 by 252, we get 4 and a remainder of 152.
The next digit of our result is 4. 
Result so far: 122959.924
If we subtract 1008 from 1160, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 12:
1520 divided by 252 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 122959.9246
Subtract 1512 from 1520 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
80 divided by 252 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 122959.9246
If we take 0 away from 80, 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 14:
800 divided by 252 is 3 with a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 122959.924603
If we take 756 away from 800, 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 15:
The number 252 fits into 440 1 times, leaving a remainder of 188.
Record the quotient 1 as the next digit in the result. 
Result so far: 122959.9246031
Subtract 252 from 440 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 16:
The number 252 fits into 1880 7 times, leaving a remainder of 116.
Record the quotient 7 as the next digit in the result. 
Result so far: 122959.92460317
Subtracting 1764 from 1880 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

After the division, we end up with 122959.92460317 and a remainder of 1.16e-07.
