13101117 divided by 42 
We want to figure out the number of times 13101117 can be divided by 42.

Step 1:
The number 42 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 42

Going ahead to step 2:
The number 42 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 42

Going ahead to step 3:
If we divide 131 by 42, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 126 from 131 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 42

Moving on to step 4:
The number 42 fits into 50 1 times, leaving a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 42 from 50 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 42

On to step 5:
If we divide 81 by 42, we get 1 and a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 311.0
If we subtract 42 from 81, we get 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 42

Advancing to step 6:
391 divided by 42 is 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 3119.0
If we take 378 away from 391, we end up with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 42

On to step 7:
42 goes into 131 3 times with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 31193.0
If we take 126 away from 131, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 42

Going ahead to step 8:
57 divided by 42 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 311931.0
Deduct 42 from 57 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
42 goes into 150 3 times with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 311931.3
The remainder is 24 after subtracting 126 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
42 goes into 240 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 311931.35
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
If we divide 300 by 42, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 311931.357
Subtracting 294 from 300 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
When dividing 60 by 42, we get 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 311931.3571
If we take 42 away from 60, we end up 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.

On to step 13:
180 divided by 42 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 311931.35714
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
The number 42 fits into 120 2 times, leaving a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 311931.357142
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 15:
360 divided by 42 is 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 311931.3571428
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 16:
42 goes into 240 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 311931.35714285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 311931.35714285 and a remainder of 3e-08.
