Let's divide 31090343 by 212
Our goal is to divide 31090343 by 212.

Moving on to step 1:
212 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 212

Moving on to step 2:
212 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
If we take 0 away from 31, we end up with 31.
Take the next digit (0) from the dividend and append it to 31, then repeat: 310 / 212

Going ahead to step 3:
212 goes into 310 1 times with a remainder of 98.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 98 after subtracting 212 from 310.
Append the next digit (9) from the dividend to 98 and continue with: 989 / 212

Let's proceed to step 4:
212 goes into 989 4 times with a remainder of 141.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 848 from 989, we get 141.
Fetch the next digit (0) from the dividend, attach it to 141 and continue: 1410 / 212

Going ahead to step 5:
If we divide 1410 by 212, we get 6 and a remainder of 138.
Record the quotient 6 as the next digit in the result. 
Result so far: 146.0
The remainder is 138 after subtracting 1272 from 1410.
Include the next digit (3) from the dividend after 138, then repeat: 1383 / 212

Going ahead to step 6:
212 goes into 1383 6 times with a remainder of 111.
The number 6 becomes the next digit in our result. 
Result so far: 1466.0
If we take 1272 away from 1383, we end up with 111.
Append the next digit (4) from the dividend to 111 and continue with: 1114 / 212

On to step 7:
1114 divided by 212 is 5 with a remainder of 54.
Put 5 as the next digit of the answer. 
Result so far: 14665.0
Subtract 1060 from 1114 to get 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 212

Advancing to step 8:
543 divided by 212 is 2 with a remainder of 119.
Record the quotient 2 as the next digit in the result. 
Result so far: 146652.0
Subtracting 424 from 543 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 9:
If we divide 1190 by 212, we get 5 and a remainder of 130.
The number 5 becomes the next digit in our result. 
Result so far: 146652.5
The remainder is 130 after subtracting 1060 from 1190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 10:
212 goes into 1300 6 times with a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 146652.56
Subtracting 1272 from 1300 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
If we divide 280 by 212, we get 1 and a remainder of 68.
The next digit of our result is 1. 
Result so far: 146652.561
Subtracting 212 from 280 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 12:
212 can be fit into 680 3 times, resulting in a remainder of 44.
The next digit of our result is 3. 
Result so far: 146652.5613
Deduct 636 from 680 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
440 divided by 212 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 146652.56132
Subtract 424 from 440 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
When dividing 160 by 212, we get 0 with a remainder of 160.
The next digit of our result is 0. 
Result so far: 146652.56132
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 15:
1600 divided by 212 is 7 with a remainder of 116.
Write down 7 as next digit of the result. 
Result so far: 146652.5613207
If we subtract 1484 from 1600, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 16:
The number 212 fits into 1160 5 times, leaving a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 146652.56132075
Subtracting 1060 from 1160 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 146652.56132075, with a leftover of 1e-07.
