We're dividing 45269979 by 310 
We want to divide 45269979 by 310.

On to step 1:
If we divide 4 by 310, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 310

Step 2:
The number 310 fits into 45 0 times, leaving a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Grab the next digit (2) from the dividend, add it to 45, then carry on: 452 / 310

Step 3:
310 can be fit into 452 1 times, resulting in a remainder of 142.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 310 from 452, we get 142.
Include the next digit (6) from the dividend after 142, then repeat: 1426 / 310

Advancing to step 4:
310 goes into 1426 4 times with a remainder of 186.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 1240 from 1426 leaves us with 186.
Take the next digit (9) from the dividend and append it to 186, then repeat: 1869 / 310

Let's proceed to step 5:
If we divide 1869 by 310, we get 6 and a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 146.0
Deduct 1860 from 1869 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 310

Step 6:
If we divide 99 by 310, we get 0 and a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 1460.0
The remainder is 99 after subtracting 0 from 99.
Include the next digit (7) from the dividend after 99, then repeat: 997 / 310

Advancing to step 7:
310 goes into 997 3 times with a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 14603.0
Deduct 930 from 997 and we're left with 67.
Grab the next digit (9) from the dividend, add it to 67, then carry on: 679 / 310

On to step 8:
310 can be fit into 679 2 times, resulting in a remainder of 59.
Write down 2 as next digit of the result. 
Result so far: 146032.0
Deduct 620 from 679 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 9:
When dividing 590 by 310, we get 1 with a remainder of 280.
The next digit of our result is 1. 
Result so far: 146032.1
If we take 310 away from 590, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 10:
310 can be fit into 2800 9 times, resulting in a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 146032.19
Subtract 2790 from 2800 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.

Moving on to step 11:
100 divided by 310 is 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 146032.19
The remainder is 100 after subtracting 0 from 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 12:
310 can be fit into 1000 3 times, resulting in a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 146032.1903
The remainder is 70 after subtracting 930 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
If we divide 700 by 310, we get 2 and a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 146032.19032
Deduct 620 from 700 and we're left 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:
When dividing 800 by 310, we get 2 with a remainder of 180.
The next digit of our result is 2. 
Result so far: 146032.190322
The remainder is 180 after subtracting 620 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

After the division, we end up with 146032.190322 and a remainder of 1.8e-05.
