We look at the division of 75315154 by 346 
We're looking to find how many times 346 goes into 75315154.

Step 1:
If we divide 7 by 346, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 346

Going ahead to step 2:
The number 346 fits into 75 0 times, leaving a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Grab the next digit (3) from the dividend, add it to 75, then carry on: 753 / 346

Step 3:
If we divide 753 by 346, we get 2 and a remainder of 61.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 692 from 753 leaves us with 61.
Bring next digit (1) of the dividend behind the 61 and repeat the process: 611 / 346

Moving on to step 4:
The number 346 fits into 611 1 times, leaving a remainder of 265.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 346 from 611 leaves us with 265.
Grab the next digit (5) from the dividend, add it to 265, then carry on: 2655 / 346

On to step 5:
2655 divided by 346 is 7 with a remainder of 233.
The next digit of our result is 7. 
Result so far: 217.0
Deduct 2422 from 2655 and we're left with 233.
Include the next digit (1) from the dividend after 233, then repeat: 2331 / 346

Let's proceed to step 6:
346 can be fit into 2331 6 times, resulting in a remainder of 255.
Use 6 as the next digit of our solution. 
Result so far: 2176.0
If we take 2076 away from 2331, we end up with 255.
Append the next digit (5) from the dividend to 255 and continue with: 2555 / 346

Step 7:
When dividing 2555 by 346, we get 7 with a remainder of 133.
Use 7 as the next digit of our solution. 
Result so far: 21767.0
If we subtract 2422 from 2555, we get 133.
Fetch the next digit (4) from the dividend, attach it to 133 and continue: 1334 / 346

Let's proceed to step 8:
346 can be fit into 1334 3 times, resulting in a remainder of 296.
Put 3 as the next digit of the answer. 
Result so far: 217673.0
Subtracting 1038 from 1334 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 9:
346 goes into 2960 8 times with a remainder of 192.
Use 8 as the next digit of our solution. 
Result so far: 217673.8
Deduct 2768 from 2960 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 10:
The number 346 fits into 1920 5 times, leaving a remainder of 190.
Record the quotient 5 as the next digit in the result. 
Result so far: 217673.85
If we take 1730 away from 1920, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 11:
If we divide 1900 by 346, we get 5 and a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 217673.855
Subtracting 1730 from 1900 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final outcome is 217673.855, with a leftover of 0.017.
