We look at the division of 45213287 by 310 
We want to figure out the number of times 45213287 can be divided by 310.

Advancing to step 1:
When dividing 4 by 310, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 310

On to step 2:
45 divided by 310 is 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 310

Moving on to step 3:
310 can be fit into 452 1 times, resulting in a remainder of 142.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 310 from 452 to get 142.
Fetch the next digit (1) from the dividend, attach it to 142 and continue: 1421 / 310

Let's proceed to step 4:
310 goes into 1421 4 times with a remainder of 181.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 181 after subtracting 1240 from 1421.
Append the next digit (3) from the dividend to 181 and continue with: 1813 / 310

Advancing to step 5:
310 can be fit into 1813 5 times, resulting in a remainder of 263.
Put 5 as the next digit of the answer. 
Result so far: 145.0
The remainder is 263 after subtracting 1550 from 1813.
Fetch the next digit (2) from the dividend, attach it to 263 and continue: 2632 / 310

Step 6:
310 can be fit into 2632 8 times, resulting in a remainder of 152.
The next digit of our result is 8. 
Result so far: 1458.0
The remainder is 152 after subtracting 2480 from 2632.
Fetch the next digit (8) from the dividend, attach it to 152 and continue: 1528 / 310

Advancing to step 7:
310 goes into 1528 4 times with a remainder of 288.
Put 4 as the next digit of the answer. 
Result so far: 14584.0
Subtract 1240 from 1528 to get 288.
Fetch the next digit (7) from the dividend, attach it to 288 and continue: 2887 / 310

Advancing to step 8:
310 can be fit into 2887 9 times, resulting in a remainder of 97.
Write down 9 as next digit of the result. 
Result so far: 145849.0
If we take 2790 away from 2887, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 9:
310 can be fit into 970 3 times, resulting in a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 145849.3
The remainder is 40 after subtracting 930 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
If we divide 400 by 310, we get 1 and a remainder of 90.
Use 1 as the next digit of our solution. 
Result so far: 145849.31
Subtract 310 from 400 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 11:
310 goes into 900 2 times with a remainder of 280.
Put 2 as the next digit of the answer. 
Result so far: 145849.312
If we subtract 620 from 900, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 12:
The number 310 fits into 2800 9 times, leaving a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 145849.3129
If we take 2790 away from 2800, we end up 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.

Advancing to step 13:
310 can be fit into 100 0 times, resulting in a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 145849.3129
Deduct 0 from 100 and we're left with 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 14:
If we divide 1000 by 310, we get 3 and a remainder of 70.
Write down 3 as next digit of the result. 
Result so far: 145849.312903
Subtracting 930 from 1000 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 15:
The number 310 fits into 700 2 times, leaving a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 145849.3129032
If we take 620 away from 700, 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.

Moving on to step 16:
310 can be fit into 800 2 times, resulting in a remainder of 180.
Write down 2 as next digit of the result. 
Result so far: 145849.31290322
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.

In conclusion, the division gives 145849.31290322 with a balance of 1.8e-07.
