Let's divide 387204 by 91
We want to figure out the number of times 387204 can be divided by 91.

Step 1:
The number 91 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 91

Step 2:
91 can be fit into 38 0 times, resulting in a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Append the next digit (7) from the dividend to 38 and continue with: 387 / 91

Advancing to step 3:
If we divide 387 by 91, we get 4 and a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 364 from 387, we get 23.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 91

Going ahead to step 4:
The number 91 fits into 232 2 times, leaving a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Deduct 182 from 232 and we're left with 50.
Bring next digit (0) of the dividend behind the 50 and repeat the process: 500 / 91

Let's proceed to step 5:
91 can be fit into 500 5 times, resulting in a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 425.0
If we take 455 away from 500, we end up with 45.
Grab the next digit (4) from the dividend, add it to 45, then carry on: 454 / 91

Moving on to step 6:
When dividing 454 by 91, we get 4 with a remainder of 90.
Use 4 as the next digit of our solution. 
Result so far: 4254.0
If we take 364 away from 454, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 7:
91 goes into 900 9 times with a remainder of 81.
Record the quotient 9 as the next digit in the result. 
Result so far: 4254.9
The remainder is 81 after subtracting 819 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 8:
91 can be fit into 810 8 times, resulting in a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 4254.98
Subtract 728 from 810 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
91 goes into 820 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 4254.989
The remainder is 1 after subtracting 819 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
When dividing 10 by 91, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 4254.989
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
91 goes into 100 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 4254.98901
If we take 91 away from 100, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 12:
91 can be fit into 90 0 times, resulting in a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 4254.98901
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 13:
The number 91 fits into 900 9 times, leaving a remainder of 81.
Put 9 as the next digit of the answer. 
Result so far: 4254.9890109
Subtract 819 from 900 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 14:
The number 91 fits into 810 8 times, leaving a remainder of 82.
The next digit of our result is 8. 
Result so far: 4254.98901098
Subtract 728 from 810 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

The quotient of the division is 4254.98901098, and the remainder is 8.2e-08.
