We're dividing 6743729 by 161 
We want to figure out the number of times 6743729 can be divided by 161.

On to step 1:
6 divided by 161 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 161

Step 2:
161 goes into 67 0 times with a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Take the next digit (4) from the dividend and append it to 67, then repeat: 674 / 161

Advancing to step 3:
161 goes into 674 4 times with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 30 after subtracting 644 from 674.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 161

Going ahead to step 4:
303 divided by 161 is 1 with a remainder of 142.
Put 1 as the next digit of the answer. 
Result so far: 41.0
Subtract 161 from 303 to get 142.
Append the next digit (7) from the dividend to 142 and continue with: 1427 / 161

Step 5:
161 can be fit into 1427 8 times, resulting in a remainder of 139.
The next digit of our result is 8. 
Result so far: 418.0
The remainder is 139 after subtracting 1288 from 1427.
Append the next digit (2) from the dividend to 139 and continue with: 1392 / 161

Advancing to step 6:
When dividing 1392 by 161, we get 8 with a remainder of 104.
Record the quotient 8 as the next digit in the result. 
Result so far: 4188.0
Deduct 1288 from 1392 and we're left with 104.
Include the next digit (9) from the dividend after 104, then repeat: 1049 / 161

On to step 7:
If we divide 1049 by 161, we get 6 and a remainder of 83.
Record the quotient 6 as the next digit in the result. 
Result so far: 41886.0
If we take 966 away from 1049, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 8:
830 divided by 161 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 41886.5
Deduct 805 from 830 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
161 can be fit into 250 1 times, resulting in a remainder of 89.
Use 1 as the next digit of our solution. 
Result so far: 41886.51
The remainder is 89 after subtracting 161 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 10:
If we divide 890 by 161, we get 5 and a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 41886.515
If we subtract 805 from 890, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 11:
If we divide 850 by 161, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 41886.5155
Subtracting 805 from 850 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Our division results in 41886.5155 with a remaining 0.00045.
