121499 ÷ 91 
Our goal is to divide 121499 by 91.

Going ahead to step 1:
The number 91 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 91

Moving on to step 2:
If we divide 12 by 91, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 91

Moving on to step 3:
91 goes into 121 1 times with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 91 from 121 to get 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 91

Advancing to step 4:
304 divided by 91 is 3 with a remainder of 31.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 273 from 304 leaves us with 31.
Take the next digit (9) from the dividend and append it to 31, then repeat: 319 / 91

Let's proceed to step 5:
When dividing 319 by 91, we get 3 with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 133.0
If we take 273 away from 319, we end up with 46.
Include the next digit (9) from the dividend after 46, then repeat: 469 / 91

Going ahead to step 6:
91 can be fit into 469 5 times, resulting in a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 1335.0
The remainder is 14 after subtracting 455 from 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
91 can be fit into 140 1 times, resulting in a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 1335.1
If we take 91 away from 140, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 8:
91 can be fit into 490 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 1335.15
Subtracting 455 from 490 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
If we divide 350 by 91, we get 3 and a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 1335.153
Deduct 273 from 350 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 10:
If we divide 770 by 91, we get 8 and a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 1335.1538
The remainder is 42 after subtracting 728 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
91 goes into 420 4 times with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 1335.15384
Subtract 364 from 420 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
If we divide 560 by 91, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 1335.153846
Subtract 546 from 560 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 13:
91 goes into 140 1 times with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 1335.1538461
Deduct 91 from 140 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 14:
When dividing 490 by 91, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 1335.15384615
Subtract 455 from 490 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 1335.15384615 with a remaining 3.5e-08.
