31218879 ÷ 346 
We want to divide 31218879 by 346.

Let's proceed to step 1:
346 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 346

Going ahead to step 2:
31 divided by 346 is 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 346

Moving on to step 3:
The number 346 fits into 312 0 times, leaving a remainder of 312.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 312 after subtracting 0 from 312.
Take the next digit (1) from the dividend and append it to 312, then repeat: 3121 / 346

Step 4:
346 can be fit into 3121 9 times, resulting in a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 3114 from 3121 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 346

Going ahead to step 5:
If we divide 78 by 346, we get 0 and a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 90.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 346

Moving on to step 6:
The number 346 fits into 788 2 times, leaving a remainder of 96.
The number 2 becomes the next digit in our result. 
Result so far: 902.0
Subtract 692 from 788 to get 96.
Grab the next digit (7) from the dividend, add it to 96, then carry on: 967 / 346

Step 7:
346 goes into 967 2 times with a remainder of 275.
The number 2 becomes the next digit in our result. 
Result so far: 9022.0
If we subtract 692 from 967, we get 275.
Append the next digit (9) from the dividend to 275 and continue with: 2759 / 346

Let's proceed to step 8:
346 goes into 2759 7 times with a remainder of 337.
Put 7 as the next digit of the answer. 
Result so far: 90227.0
If we take 2422 away from 2759, we end up with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Let's proceed to step 9:
346 goes into 3370 9 times with a remainder of 256.
Write down 9 as next digit of the result. 
Result so far: 90227.9
The remainder is 256 after subtracting 3114 from 3370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 10:
If we divide 2560 by 346, we get 7 and a remainder of 138.
Use 7 as the next digit of our solution. 
Result so far: 90227.97
If we subtract 2422 from 2560, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 11:
346 can be fit into 1380 3 times, resulting in a remainder of 342.
The next digit of our result is 3. 
Result so far: 90227.973
If we take 1038 away from 1380, we end up with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 12:
When dividing 3420 by 346, we get 9 with a remainder of 306.
Put 9 as the next digit of the answer. 
Result so far: 90227.9739
Subtracting 3114 from 3420 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 13:
When dividing 3060 by 346, we get 8 with a remainder of 292.
Use 8 as the next digit of our solution. 
Result so far: 90227.97398
If we take 2768 away from 3060, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 14:
The number 346 fits into 2920 8 times, leaving a remainder of 152.
Use 8 as the next digit of our solution. 
Result so far: 90227.973988
Subtracting 2768 from 2920 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

The quotient of the division is 90227.973988, and the remainder is 1.52e-05.
