We divide 121471 by 31
We want to figure out the number of times 121471 can be divided by 31.

On to step 1:
1 divided by 31 is 0 with 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.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 31

On to step 2:
12 divided by 31 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 31

Going ahead to step 3:
31 can be fit into 121 3 times, resulting in a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 93 away from 121, we end up with 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 31

Let's proceed to step 4:
The number 31 fits into 284 9 times, leaving a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Deduct 279 from 284 and we're left with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 31

Going ahead to step 5:
The number 31 fits into 57 1 times, leaving a remainder of 26.
The next digit of our result is 1. 
Result so far: 391.0
Subtract 31 from 57 to get 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 31

Advancing to step 6:
The number 31 fits into 261 8 times, leaving a remainder of 13.
Put 8 as the next digit of the answer. 
Result so far: 3918.0
Subtracting 248 from 261 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.

Moving on to step 7:
31 goes into 130 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 3918.4
If we take 124 away from 130, we end up 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.

Moving on to step 8:
31 goes into 60 1 times with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 3918.41
Deduct 31 from 60 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 9:
The number 31 fits into 290 9 times, leaving a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 3918.419
Deduct 279 from 290 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 10:
110 divided by 31 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 3918.4193
If we take 93 away from 110, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 11:
31 goes into 170 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 3918.41935
If we subtract 155 from 170, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
31 goes into 150 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 3918.419354
Subtracting 124 from 150 leaves us 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 31 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 3918.4193548
Deduct 248 from 260 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
31 can be fit into 120 3 times, resulting in a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 3918.41935483
If we subtract 93 from 120, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

In conclusion, the division gives 3918.41935483 with a balance of 2.7e-08.
