86711429 ÷ 353 
Our goal is to divide 86711429 by 353.

On to step 1:
If we divide 8 by 353, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 353

Advancing to step 2:
The number 353 fits into 86 0 times, leaving a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Bring next digit (7) of the dividend behind the 86 and repeat the process: 867 / 353

On to step 3:
The number 353 fits into 867 2 times, leaving a remainder of 161.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 706 away from 867, we end up with 161.
Take the next digit (1) from the dividend and append it to 161, then repeat: 1611 / 353

Going ahead to step 4:
When dividing 1611 by 353, we get 4 with a remainder of 199.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we take 1412 away from 1611, we end up with 199.
Take the next digit (1) from the dividend and append it to 199, then repeat: 1991 / 353

Let's proceed to step 5:
1991 divided by 353 is 5 with a remainder of 226.
Use 5 as the next digit of our solution. 
Result so far: 245.0
Deduct 1765 from 1991 and we're left with 226.
Take the next digit (4) from the dividend and append it to 226, then repeat: 2264 / 353

Let's proceed to step 6:
353 goes into 2264 6 times with a remainder of 146.
Put 6 as the next digit of the answer. 
Result so far: 2456.0
If we subtract 2118 from 2264, we get 146.
Take the next digit (2) from the dividend and append it to 146, then repeat: 1462 / 353

Let's proceed to step 7:
When dividing 1462 by 353, we get 4 with a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 24564.0
Subtract 1412 from 1462 to get 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 353

Moving on to step 8:
353 can be fit into 509 1 times, resulting in a remainder of 156.
Write down 1 as next digit of the result. 
Result so far: 245641.0
Subtracting 353 from 509 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 9:
If we divide 1560 by 353, we get 4 and a remainder of 148.
Write down 4 as next digit of the result. 
Result so far: 245641.4
Subtract 1412 from 1560 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 10:
If we divide 1480 by 353, we get 4 and a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 245641.44
Subtracting 1412 from 1480 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

In conclusion, the division gives 245641.44 with a balance of 0.068.
