45132274 ÷ 309 
We want to divide 45132274 by 309.

Advancing to step 1:
309 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 309

Moving on to step 2:
If we divide 45 by 309, we get 0 and a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 309

Advancing to step 3:
The number 309 fits into 451 1 times, leaving a remainder of 142.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 142 after subtracting 309 from 451.
Grab the next digit (3) from the dividend, add it to 142, then carry on: 1423 / 309

Step 4:
If we divide 1423 by 309, we get 4 and a remainder of 187.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 187 after subtracting 1236 from 1423.
Take the next digit (2) from the dividend and append it to 187, then repeat: 1872 / 309

Going ahead to step 5:
1872 divided by 309 is 6 with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 146.0
Subtracting 1854 from 1872 leaves us with 18.
Take the next digit (2) from the dividend and append it to 18, then repeat: 182 / 309

Step 6:
309 goes into 182 0 times with a remainder of 182.
Record the quotient 0 as the next digit in the result. 
Result so far: 1460.0
The remainder is 182 after subtracting 0 from 182.
Append the next digit (7) from the dividend to 182 and continue with: 1827 / 309

Let's proceed to step 7:
If we divide 1827 by 309, we get 5 and a remainder of 282.
Record the quotient 5 as the next digit in the result. 
Result so far: 14605.0
Deduct 1545 from 1827 and we're left with 282.
Take the next digit (4) from the dividend and append it to 282, then repeat: 2824 / 309

Going ahead to step 8:
309 can be fit into 2824 9 times, resulting in a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 146059.0
The remainder is 43 after subtracting 2781 from 2824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 9:
309 can be fit into 430 1 times, resulting in a remainder of 121.
The next digit of our result is 1. 
Result so far: 146059.1
If we subtract 309 from 430, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 10:
309 goes into 1210 3 times with a remainder of 283.
The number 3 becomes the next digit in our result. 
Result so far: 146059.13
If we take 927 away from 1210, we end up with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Advancing to step 11:
2830 divided by 309 is 9 with a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 146059.139
If we subtract 2781 from 2830, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 12:
309 goes into 490 1 times with a remainder of 181.
Record the quotient 1 as the next digit in the result. 
Result so far: 146059.1391
Subtracting 309 from 490 leaves us with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 13:
309 can be fit into 1810 5 times, resulting in a remainder of 265.
Put 5 as the next digit of the answer. 
Result so far: 146059.13915
If we take 1545 away from 1810, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 14:
The number 309 fits into 2650 8 times, leaving a remainder of 178.
Write down 8 as next digit of the result. 
Result so far: 146059.139158
Deduct 2472 from 2650 and we're left with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 15:
When dividing 1780 by 309, we get 5 with a remainder of 235.
Use 5 as the next digit of our solution. 
Result so far: 146059.1391585
Subtract 1545 from 1780 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 16:
When dividing 2350 by 309, we get 7 with a remainder of 187.
Put 7 as the next digit of the answer. 
Result so far: 146059.13915857
Deduct 2163 from 2350 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

The final outcome is 146059.13915857, with a leftover of 1.87e-07.
