351124 ÷ 31 
We're looking to find how many times 31 goes into 351124.

Moving on to step 1:
The number 31 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 31

Advancing to step 2:
If we divide 35 by 31, we get 1 and a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 31 from 35 leaves us with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 31

Step 3:
When dividing 41 by 31, we get 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 31 from 41 to get 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 31

On to step 4:
When dividing 101 by 31, we get 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 113.0
Subtract 93 from 101 to get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 31

Step 5:
31 goes into 82 2 times with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 1132.0
If we take 62 away from 82, we end up with 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 31

Step 6:
31 can be fit into 204 6 times, resulting in a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 11326.0
Subtracting 186 from 204 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
The number 31 fits into 180 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 11326.5
Deduct 155 from 180 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
31 can be fit into 250 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 11326.58
Subtract 248 from 250 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
31 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 11326.58
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
When dividing 200 by 31, we get 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 11326.5806
If we subtract 186 from 200, we 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.

Going ahead to step 11:
The number 31 fits into 140 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 11326.58064
The remainder is 16 after subtracting 124 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
31 can be fit into 160 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 11326.580645
The remainder is 5 after subtracting 155 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
31 can be fit into 50 1 times, resulting in a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 11326.5806451
Subtracting 31 from 50 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 14:
If we divide 190 by 31, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 11326.58064516
Subtracting 186 from 190 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 11326.58064516 and a remainder of 4e-09.
