31123947 ÷ 135 
Let's see how many times 135 fits into 31123947.

Advancing to step 1:
135 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 135

Advancing to step 2:
If we divide 31 by 135, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 135

Let's proceed to step 3:
The number 135 fits into 311 2 times, leaving a remainder of 41.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 270 from 311, we get 41.
Take the next digit (2) from the dividend and append it to 41, then repeat: 412 / 135

Advancing to step 4:
135 goes into 412 3 times with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
The remainder is 7 after subtracting 405 from 412.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 135

Going ahead to step 5:
73 divided by 135 is 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 230.0
Subtract 0 from 73 to get 73.
Fetch the next digit (9) from the dividend, attach it to 73 and continue: 739 / 135

Moving on to step 6:
The number 135 fits into 739 5 times, leaving a remainder of 64.
Use 5 as the next digit of our solution. 
Result so far: 2305.0
Subtracting 675 from 739 leaves us with 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 135

Moving on to step 7:
135 goes into 644 4 times with a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 23054.0
Subtracting 540 from 644 leaves us with 104.
Fetch the next digit (7) from the dividend, attach it to 104 and continue: 1047 / 135

Moving on to step 8:
1047 divided by 135 is 7 with a remainder of 102.
Put 7 as the next digit of the answer. 
Result so far: 230547.0
Deduct 945 from 1047 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 9:
If we divide 1020 by 135, we get 7 and a remainder of 75.
Record the quotient 7 as the next digit in the result. 
Result so far: 230547.7
Subtract 945 from 1020 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 10:
135 goes into 750 5 times with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 230547.75
Deduct 675 from 750 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 11:
135 goes into 750 5 times with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 230547.755
Deduct 675 from 750 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Our division results in 230547.755 with a remaining 0.0075.
