We're dividing 31388435 by 117 
Our goal is to divide 31388435 by 117.

On to step 1:
The number 117 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 117

Let's proceed to step 2:
117 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 117

Moving on to step 3:
313 divided by 117 is 2 with a remainder of 79.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 79 after subtracting 234 from 313.
Bring next digit (8) of the dividend behind the 79 and repeat the process: 798 / 117

Going ahead to step 4:
117 can be fit into 798 6 times, resulting in a remainder of 96.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we subtract 702 from 798, we get 96.
Bring next digit (8) of the dividend behind the 96 and repeat the process: 968 / 117

Advancing to step 5:
117 goes into 968 8 times with a remainder of 32.
The next digit of our result is 8. 
Result so far: 268.0
Deduct 936 from 968 and we're left with 32.
Grab the next digit (4) from the dividend, add it to 32, then carry on: 324 / 117

Moving on to step 6:
117 can be fit into 324 2 times, resulting in a remainder of 90.
Use 2 as the next digit of our solution. 
Result so far: 2682.0
Subtract 234 from 324 to get 90.
Fetch the next digit (3) from the dividend, attach it to 90 and continue: 903 / 117

Advancing to step 7:
If we divide 903 by 117, we get 7 and a remainder of 84.
Record the quotient 7 as the next digit in the result. 
Result so far: 26827.0
Subtract 819 from 903 to get 84.
Append the next digit (5) from the dividend to 84 and continue with: 845 / 117

Let's proceed to step 8:
117 can be fit into 845 7 times, resulting in a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 268277.0
Deduct 819 from 845 and we're left 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.

On to step 9:
The number 117 fits into 260 2 times, leaving a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 268277.2
Subtract 234 from 260 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
117 goes into 260 2 times with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 268277.22
Subtracting 234 from 260 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.

After the division, we end up with 268277.22 and a remainder of 0.026.
