We're dividing 486187 by 91 
We want to figure out the number of times 486187 can be divided by 91.

Advancing to step 1:
The number 91 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 91

Let's proceed to step 2:
91 goes into 48 0 times with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Take the next digit (6) from the dividend and append it to 48, then repeat: 486 / 91

Let's proceed to step 3:
91 can be fit into 486 5 times, resulting in a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 455 from 486 and we're left with 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 91

Step 4:
The number 91 fits into 311 3 times, leaving a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Subtract 273 from 311 to get 38.
Fetch the next digit (8) from the dividend, attach it to 38 and continue: 388 / 91

Advancing to step 5:
91 goes into 388 4 times with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 534.0
If we take 364 away from 388, we end up with 24.
Append the next digit (7) from the dividend to 24 and continue with: 247 / 91

Advancing to step 6:
91 goes into 247 2 times with a remainder of 65.
Write down 2 as next digit of the result. 
Result so far: 5342.0
Deduct 182 from 247 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 7:
If we divide 650 by 91, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 5342.7
Subtracting 637 from 650 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 8:
When dividing 130 by 91, we get 1 with a remainder of 39.
The next digit of our result is 1. 
Result so far: 5342.71
If we subtract 91 from 130, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 9:
91 goes into 390 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 5342.714
Deduct 364 from 390 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 10:
91 can be fit into 260 2 times, resulting in a remainder of 78.
The next digit of our result is 2. 
Result so far: 5342.7142
If we take 182 away from 260, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 11:
When dividing 780 by 91, we get 8 with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 5342.71428
If we take 728 away from 780, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 12:
If we divide 520 by 91, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 5342.714285
The remainder is 65 after subtracting 455 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 13:
The number 91 fits into 650 7 times, leaving a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 5342.7142857
The remainder is 13 after subtracting 637 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 14:
The number 91 fits into 130 1 times, leaving a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 5342.71428571
Subtract 91 from 130 to get 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 quotient of the division is 5342.71428571, and the remainder is 3.9e-08.
