31219 ÷ 91 
We want to divide 31219 by 91.

Step 1:
If we divide 3 by 91, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 91

Advancing to step 2:
91 can be fit into 31 0 times, resulting in a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 91

Step 3:
When dividing 312 by 91, we get 3 with a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 273 away from 312, we end up with 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 91

Let's proceed to step 4:
91 can be fit into 391 4 times, resulting in a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 34.0
If we take 364 away from 391, we end up with 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 91

On to step 5:
279 divided by 91 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 343.0
Subtracting 273 from 279 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 6:
If we divide 60 by 91, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 343.0
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
If we divide 600 by 91, we get 6 and a remainder of 54.
Write down 6 as next digit of the result. 
Result so far: 343.06
Deduct 546 from 600 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 8:
540 divided by 91 is 5 with a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 343.065
Subtracting 455 from 540 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 9:
The number 91 fits into 850 9 times, leaving a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 343.0659
If we subtract 819 from 850, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 10:
When dividing 310 by 91, we get 3 with a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 343.06593
Deduct 273 from 310 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 11:
91 can be fit into 370 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 343.065934
Deduct 364 from 370 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
The number 91 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 343.065934
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
91 can be fit into 600 6 times, resulting in a remainder of 54.
The next digit of our result is 6. 
Result so far: 343.06593406
The remainder is 54 after subtracting 546 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 343.06593406 with a remainder of 5.4e-08.
