3739 ÷ 90 
We want to figure out the number of times 3739 can be divided by 90.

Going ahead to step 1:
90 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 90

Let's proceed to step 2:
37 divided by 90 is 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Append the next digit (3) from the dividend to 37 and continue with: 373 / 90

Step 3:
373 divided by 90 is 4 with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 360 away from 373, we end up with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 90

On to step 4:
90 can be fit into 139 1 times, resulting in a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we take 90 away from 139, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 5:
490 divided by 90 is 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 41.5
If we subtract 450 from 490, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 6:
90 goes into 400 4 times with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 41.54
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
90 goes into 400 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 41.544
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 41.544 with a balance of 0.004.
