We're dividing 42149211 by 320 
We're looking to find how many times 320 goes into 42149211.

Let's proceed to step 1:
320 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 320

Advancing to step 2:
320 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 320

Moving on to step 3:
421 divided by 320 is 1 with a remainder of 101.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 101 after subtracting 320 from 421.
Bring next digit (4) of the dividend behind the 101 and repeat the process: 1014 / 320

On to step 4:
When dividing 1014 by 320, we get 3 with a remainder of 54.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 960 from 1014 and we're left with 54.
Bring next digit (9) of the dividend behind the 54 and repeat the process: 549 / 320

Advancing to step 5:
When dividing 549 by 320, we get 1 with a remainder of 229.
Put 1 as the next digit of the answer. 
Result so far: 131.0
If we subtract 320 from 549, we get 229.
Take the next digit (2) from the dividend and append it to 229, then repeat: 2292 / 320

On to step 6:
320 can be fit into 2292 7 times, resulting in a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 1317.0
If we take 2240 away from 2292, we end up with 52.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 320

Step 7:
The number 320 fits into 521 1 times, leaving a remainder of 201.
Put 1 as the next digit of the answer. 
Result so far: 13171.0
Deduct 320 from 521 and we're left with 201.
Bring next digit (1) of the dividend behind the 201 and repeat the process: 2011 / 320

On to step 8:
320 goes into 2011 6 times with a remainder of 91.
Use 6 as the next digit of our solution. 
Result so far: 131716.0
Subtracting 1920 from 2011 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 9:
If we divide 910 by 320, we get 2 and a remainder of 270.
Write down 2 as next digit of the result. 
Result so far: 131716.2
If we subtract 640 from 910, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 10:
When dividing 2700 by 320, we get 8 with a remainder of 140.
Put 8 as the next digit of the answer. 
Result so far: 131716.28
Subtract 2560 from 2700 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
When dividing 1400 by 320, we get 4 with a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 131716.284
Deduct 1280 from 1400 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 12:
1200 divided by 320 is 3 with a remainder of 240.
Use 3 as the next digit of our solution. 
Result so far: 131716.2843
If we subtract 960 from 1200, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 13:
When dividing 2400 by 320, we get 7 with a remainder of 160.
The next digit of our result is 7. 
Result so far: 131716.28437
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.

Going ahead to step 14:
1600 divided by 320 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 131716.284375
If we subtract 1600 from 1600, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 15:
0 divided by 320 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 131716.284375
Subtract 0 from 0 to get 0.
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 16:
320 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 131716.284375
If we subtract 0 from 0, we get 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 131716.284375 and a remainder of 0.0.
