Let's divide 186121 by 91
We want to figure out the number of times 186121 can be divided by 91.

On to step 1:
91 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 91

Moving on to step 2:
The number 91 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 91

Moving on to step 3:
91 can be fit into 186 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 182 from 186 leaves us with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 91

Let's proceed to step 4:
41 divided by 91 is 0 with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Deduct 0 from 41 and we're left with 41.
Grab the next digit (2) from the dividend, add it to 41, then carry on: 412 / 91

Step 5:
412 divided by 91 is 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 204.0
Deduct 364 from 412 and we're left with 48.
Grab the next digit (1) from the dividend, add it to 48, then carry on: 481 / 91

Step 6:
91 can be fit into 481 5 times, resulting in a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 2045.0
Subtract 455 from 481 to get 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 7:
91 can be fit into 260 2 times, resulting in a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 2045.2
The remainder is 78 after subtracting 182 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 8:
The number 91 fits into 780 8 times, leaving a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 2045.28
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.

Moving on to step 9:
If we divide 520 by 91, we get 5 and a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 2045.285
Subtract 455 from 520 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 10:
91 can be fit into 650 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 2045.2857
Deduct 637 from 650 and we're left 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.

Advancing to step 11:
If we divide 130 by 91, we get 1 and a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 2045.28571
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.

Moving on to step 12:
91 can be fit into 390 4 times, resulting in a remainder of 26.
The next digit of our result is 4. 
Result so far: 2045.285714
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 13:
260 divided by 91 is 2 with a remainder of 78.
The next digit of our result is 2. 
Result so far: 2045.2857142
Subtracting 182 from 260 leaves us 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.

Advancing to step 14:
91 goes into 780 8 times with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 2045.28571428
The remainder is 52 after subtracting 728 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 2045.28571428 with a remaining 5.2e-08.
