We look at the division of 438186 by 93 
We want to figure out the number of times 438186 can be divided by 93.

On to step 1:
93 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 93

Let's proceed to step 2:
43 divided by 93 is 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 93

Step 3:
438 divided by 93 is 4 with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 372 from 438, we get 66.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 93

Going ahead to step 4:
93 can be fit into 661 7 times, resulting in a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Subtracting 651 from 661 leaves us with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 93

Advancing to step 5:
93 can be fit into 108 1 times, resulting in a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 471.0
Subtracting 93 from 108 leaves us with 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 93

Advancing to step 6:
93 can be fit into 156 1 times, resulting in a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 4711.0
Subtract 93 from 156 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 7:
93 goes into 630 6 times with a remainder of 72.
The next digit of our result is 6. 
Result so far: 4711.6
Deduct 558 from 630 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 8:
93 goes into 720 7 times with a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 4711.67
The remainder is 69 after subtracting 651 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 9:
93 can be fit into 690 7 times, resulting in a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 4711.677
Subtracting 651 from 690 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final result is 4711.677 with a remainder of 0.0039.
