We look at the division of 45309621 by 337 
Our goal is to divide 45309621 by 337.

Step 1:
337 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 337

On to step 2:
If we divide 45 by 337, we get 0 and a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 337

Going ahead to step 3:
The number 337 fits into 453 1 times, leaving a remainder of 116.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 337 from 453 to get 116.
Grab the next digit (0) from the dividend, add it to 116, then carry on: 1160 / 337

Moving on to step 4:
When dividing 1160 by 337, we get 3 with a remainder of 149.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 1011 from 1160 leaves us with 149.
Take the next digit (9) from the dividend and append it to 149, then repeat: 1499 / 337

Let's proceed to step 5:
1499 divided by 337 is 4 with a remainder of 151.
Put 4 as the next digit of the answer. 
Result so far: 134.0
Deduct 1348 from 1499 and we're left with 151.
Include the next digit (6) from the dividend after 151, then repeat: 1516 / 337

Let's proceed to step 6:
The number 337 fits into 1516 4 times, leaving a remainder of 168.
The number 4 becomes the next digit in our result. 
Result so far: 1344.0
Subtract 1348 from 1516 to get 168.
Take the next digit (2) from the dividend and append it to 168, then repeat: 1682 / 337

Moving on to step 7:
If we divide 1682 by 337, we get 4 and a remainder of 334.
The next digit of our result is 4. 
Result so far: 13444.0
Subtracting 1348 from 1682 leaves us with 334.
Grab the next digit (1) from the dividend, add it to 334, then carry on: 3341 / 337

Let's proceed to step 8:
3341 divided by 337 is 9 with a remainder of 308.
Use 9 as the next digit of our solution. 
Result so far: 134449.0
The remainder is 308 after subtracting 3033 from 3341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 9:
When dividing 3080 by 337, we get 9 with a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 134449.9
Deduct 3033 from 3080 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 10:
If we divide 470 by 337, we get 1 and a remainder of 133.
Put 1 as the next digit of the answer. 
Result so far: 134449.91
Deduct 337 from 470 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

On to step 11:
337 goes into 1330 3 times with a remainder of 319.
Put 3 as the next digit of the answer. 
Result so far: 134449.913
Subtracting 1011 from 1330 leaves us with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Going ahead to step 12:
337 can be fit into 3190 9 times, resulting in a remainder of 157.
Record the quotient 9 as the next digit in the result. 
Result so far: 134449.9139
If we take 3033 away from 3190, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 13:
The number 337 fits into 1570 4 times, leaving a remainder of 222.
The number 4 becomes the next digit in our result. 
Result so far: 134449.91394
Subtracting 1348 from 1570 leaves us with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 14:
2220 divided by 337 is 6 with a remainder of 198.
Put 6 as the next digit of the answer. 
Result so far: 134449.913946
If we take 2022 away from 2220, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 15:
337 goes into 1980 5 times with a remainder of 295.
The next digit of our result is 5. 
Result so far: 134449.9139465
The remainder is 295 after subtracting 1685 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Step 16:
2950 divided by 337 is 8 with a remainder of 254.
Record the quotient 8 as the next digit in the result. 
Result so far: 134449.91394658
The remainder is 254 after subtracting 2696 from 2950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

The final result is 134449.91394658 with a remainder of 2.54e-07.
