We're dividing 386196 by 90 
We want to figure out the number of times 386196 can be divided by 90.

Step 1:
3 divided by 90 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 90

Advancing to step 2:
90 goes into 38 0 times with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 90

Let's proceed to step 3:
90 can be fit into 386 4 times, resulting in a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 360 from 386 and we're left with 26.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 90

Advancing to step 4:
When dividing 261 by 90, we get 2 with a remainder of 81.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtracting 180 from 261 leaves us with 81.
Take the next digit (9) from the dividend and append it to 81, then repeat: 819 / 90

Let's proceed to step 5:
When dividing 819 by 90, we get 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 429.0
If we take 810 away from 819, we end up with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 90

Let's proceed to step 6:
When dividing 96 by 90, we get 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 4291.0
If we take 90 away from 96, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
60 divided by 90 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 4291.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
If we divide 600 by 90, we get 6 and a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 4291.06
Subtract 540 from 600 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
600 divided by 90 is 6 with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 4291.066
If we take 540 away from 600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 4291.066, with a leftover of 0.006.
