44646539 ÷ 320 
We're looking to find how many times 320 goes into 44646539.

Moving on to step 1:
320 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 320

Moving on to step 2:
When dividing 44 by 320, we get 0 with a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Take the next digit (6) from the dividend and append it to 44, then repeat: 446 / 320

Advancing to step 3:
If we divide 446 by 320, we get 1 and a remainder of 126.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 320 from 446 and we're left with 126.
Append the next digit (4) from the dividend to 126 and continue with: 1264 / 320

Going ahead to step 4:
1264 divided by 320 is 3 with a remainder of 304.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 960 from 1264 and we're left with 304.
Take the next digit (6) from the dividend and append it to 304, then repeat: 3046 / 320

On to step 5:
The number 320 fits into 3046 9 times, leaving a remainder of 166.
Put 9 as the next digit of the answer. 
Result so far: 139.0
Deduct 2880 from 3046 and we're left with 166.
Append the next digit (5) from the dividend to 166 and continue with: 1665 / 320

Advancing to step 6:
320 goes into 1665 5 times with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 1395.0
Deduct 1600 from 1665 and we're left with 65.
Bring next digit (3) of the dividend behind the 65 and repeat the process: 653 / 320

Step 7:
If we divide 653 by 320, we get 2 and a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 13952.0
The remainder is 13 after subtracting 640 from 653.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 320

Step 8:
The number 320 fits into 139 0 times, leaving a remainder of 139.
Write down 0 as next digit of the result. 
Result so far: 139520.0
If we subtract 0 from 139, we get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Going ahead to step 9:
320 goes into 1390 4 times with a remainder of 110.
Write down 4 as next digit of the result. 
Result so far: 139520.4
Subtracting 1280 from 1390 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
If we divide 1100 by 320, we get 3 and a remainder of 140.
The next digit of our result is 3. 
Result so far: 139520.43
Subtracting 960 from 1100 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
1400 divided by 320 is 4 with a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 139520.434
Subtract 1280 from 1400 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
320 goes into 1200 3 times with a remainder of 240.
Use 3 as the next digit of our solution. 
Result so far: 139520.4343
Subtracting 960 from 1200 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 13:
2400 divided by 320 is 7 with a remainder of 160.
Record the quotient 7 as the next digit in the result. 
Result so far: 139520.43437
Subtract 2240 from 2400 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 14:
320 can be fit into 1600 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 139520.434375
The remainder is 0 after subtracting 1600 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 15:
320 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 139520.434375
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 16:
The number 320 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 139520.434375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 139520.434375 and a remainder of 0.0.
