Let's divide 97752145 by 309
Our goal is to divide 97752145 by 309.

On to step 1:
309 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 309

Advancing to step 2:
If we divide 97 by 309, we get 0 and a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 97 leaves us with 97.
Fetch the next digit (7) from the dividend, attach it to 97 and continue: 977 / 309

Step 3:
If we divide 977 by 309, we get 3 and a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 927 from 977 leaves us with 50.
Fetch the next digit (5) from the dividend, attach it to 50 and continue: 505 / 309

Moving on to step 4:
If we divide 505 by 309, we get 1 and a remainder of 196.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 309 from 505 to get 196.
Take the next digit (2) from the dividend and append it to 196, then repeat: 1962 / 309

Advancing to step 5:
309 can be fit into 1962 6 times, resulting in a remainder of 108.
Put 6 as the next digit of the answer. 
Result so far: 316.0
Subtracting 1854 from 1962 leaves us with 108.
Grab the next digit (1) from the dividend, add it to 108, then carry on: 1081 / 309

Step 6:
When dividing 1081 by 309, we get 3 with a remainder of 154.
Record the quotient 3 as the next digit in the result. 
Result so far: 3163.0
If we subtract 927 from 1081, we get 154.
Take the next digit (4) from the dividend and append it to 154, then repeat: 1544 / 309

Step 7:
If we divide 1544 by 309, we get 4 and a remainder of 308.
Write down 4 as next digit of the result. 
Result so far: 31634.0
Subtracting 1236 from 1544 leaves us with 308.
Include the next digit (5) from the dividend after 308, then repeat: 3085 / 309

Moving on to step 8:
309 goes into 3085 9 times with a remainder of 304.
Write down 9 as next digit of the result. 
Result so far: 316349.0
Deduct 2781 from 3085 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 9:
3040 divided by 309 is 9 with a remainder of 259.
Use 9 as the next digit of our solution. 
Result so far: 316349.9
The remainder is 259 after subtracting 2781 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

On to step 10:
When dividing 2590 by 309, we get 8 with a remainder of 118.
The number 8 becomes the next digit in our result. 
Result so far: 316349.98
If we subtract 2472 from 2590, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 11:
If we divide 1180 by 309, we get 3 and a remainder of 253.
Record the quotient 3 as the next digit in the result. 
Result so far: 316349.983
If we subtract 927 from 1180, we get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Moving on to step 12:
309 goes into 2530 8 times with a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 316349.9838
The remainder is 58 after subtracting 2472 from 2530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 13:
If we divide 580 by 309, we get 1 and a remainder of 271.
Put 1 as the next digit of the answer. 
Result so far: 316349.98381
Deduct 309 from 580 and we're left with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Moving on to step 14:
The number 309 fits into 2710 8 times, leaving a remainder of 238.
The number 8 becomes the next digit in our result. 
Result so far: 316349.983818
Subtracting 2472 from 2710 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 15:
If we divide 2380 by 309, we get 7 and a remainder of 217.
Record the quotient 7 as the next digit in the result. 
Result so far: 316349.9838187
Deduct 2163 from 2380 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Advancing to step 16:
309 goes into 2170 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 316349.98381877
Subtract 2163 from 2170 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 316349.98381877, and the remainder is 7e-09.
