18117352 ÷ 356 
We want to figure out the number of times 18117352 can be divided by 356.

Let's proceed to step 1:
356 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 356

Advancing to step 2:
The number 356 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 356

On to step 3:
When dividing 181 by 356, we get 0 with a remainder of 181.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 181 and we're left with 181.
Grab the next digit (1) from the dividend, add it to 181, then carry on: 1811 / 356

Let's proceed to step 4:
If we divide 1811 by 356, we get 5 and a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 1780 from 1811 leaves us with 31.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 356

Going ahead to step 5:
If we divide 317 by 356, we get 0 and a remainder of 317.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we subtract 0 from 317, we get 317.
Take the next digit (3) from the dividend and append it to 317, then repeat: 3173 / 356

Advancing to step 6:
356 goes into 3173 8 times with a remainder of 325.
The next digit of our result is 8. 
Result so far: 508.0
The remainder is 325 after subtracting 2848 from 3173.
Bring next digit (5) of the dividend behind the 325 and repeat the process: 3255 / 356

Step 7:
356 can be fit into 3255 9 times, resulting in a remainder of 51.
The next digit of our result is 9. 
Result so far: 5089.0
Deduct 3204 from 3255 and we're left with 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 356

Step 8:
356 goes into 512 1 times with a remainder of 156.
The number 1 becomes the next digit in our result. 
Result so far: 50891.0
The remainder is 156 after subtracting 356 from 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 9:
356 can be fit into 1560 4 times, resulting in a remainder of 136.
Record the quotient 4 as the next digit in the result. 
Result so far: 50891.4
Deduct 1424 from 1560 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 10:
When dividing 1360 by 356, we get 3 with a remainder of 292.
The number 3 becomes the next digit in our result. 
Result so far: 50891.43
If we subtract 1068 from 1360, we get 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 11:
2920 divided by 356 is 8 with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 50891.438
If we subtract 2848 from 2920, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
The number 356 fits into 720 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 50891.4382
The remainder is 8 after subtracting 712 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
If we divide 80 by 356, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 50891.4382
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 14:
356 goes into 800 2 times with a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 50891.438202
Subtract 712 from 800 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 15:
356 goes into 880 2 times with a remainder of 168.
Record the quotient 2 as the next digit in the result. 
Result so far: 50891.4382022
If we subtract 712 from 880, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final outcome is 50891.4382022, with a leftover of 1.68e-06.
