353915 ÷ 69 
Our goal is to divide 353915 by 69.

On to step 1:
If we divide 3 by 69, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 69

Moving on to step 2:
69 goes into 35 0 times with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Append the next digit (3) from the dividend to 35 and continue with: 353 / 69

Moving on to step 3:
When dividing 353 by 69, we get 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 345 away from 353, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 69

On to step 4:
69 goes into 89 1 times with a remainder of 20.
The next digit of our result is 1. 
Result so far: 51.0
Subtracting 69 from 89 leaves us with 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 69

Going ahead to step 5:
69 goes into 201 2 times with a remainder of 63.
Use 2 as the next digit of our solution. 
Result so far: 512.0
Subtract 138 from 201 to get 63.
Take the next digit (5) from the dividend and append it to 63, then repeat: 635 / 69

Advancing to step 6:
When dividing 635 by 69, we get 9 with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 5129.0
Deduct 621 from 635 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
When dividing 140 by 69, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 5129.2
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
20 divided by 69 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 5129.2
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
200 divided by 69 is 2 with a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 5129.202
If we take 138 away from 200, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 10:
620 divided by 69 is 8 with a remainder of 68.
The next digit of our result is 8. 
Result so far: 5129.2028
The remainder is 68 after subtracting 552 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 11:
The number 69 fits into 680 9 times, leaving a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 5129.20289
If we take 621 away from 680, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 12:
69 can be fit into 590 8 times, resulting in a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 5129.202898
The remainder is 38 after subtracting 552 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 13:
When dividing 380 by 69, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 5129.2028985
The remainder is 35 after subtracting 345 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 14:
69 goes into 350 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 5129.20289855
The remainder is 5 after subtracting 345 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 5129.20289855, with a leftover of 5e-09.
