86074258 divided by 353 
We want to figure out the number of times 86074258 can be divided by 353.

Going ahead to step 1:
8 divided by 353 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 353

Moving on to step 2:
86 divided by 353 is 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Include the next digit (0) from the dividend after 86, then repeat: 860 / 353

On to step 3:
353 goes into 860 2 times with a remainder of 154.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 706 from 860 and we're left with 154.
Append the next digit (7) from the dividend to 154 and continue with: 1547 / 353

Going ahead to step 4:
If we divide 1547 by 353, we get 4 and a remainder of 135.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we take 1412 away from 1547, we end up with 135.
Grab the next digit (4) from the dividend, add it to 135, then carry on: 1354 / 353

Advancing to step 5:
If we divide 1354 by 353, we get 3 and a remainder of 295.
Record the quotient 3 as the next digit in the result. 
Result so far: 243.0
Subtract 1059 from 1354 to get 295.
Include the next digit (2) from the dividend after 295, then repeat: 2952 / 353

Advancing to step 6:
2952 divided by 353 is 8 with a remainder of 128.
The number 8 becomes the next digit in our result. 
Result so far: 2438.0
Subtracting 2824 from 2952 leaves us with 128.
Append the next digit (5) from the dividend to 128 and continue with: 1285 / 353

Moving on to step 7:
When dividing 1285 by 353, we get 3 with a remainder of 226.
Write down 3 as next digit of the result. 
Result so far: 24383.0
Deduct 1059 from 1285 and we're left with 226.
Take the next digit (8) from the dividend and append it to 226, then repeat: 2268 / 353

Let's proceed to step 8:
The number 353 fits into 2268 6 times, leaving a remainder of 150.
The number 6 becomes the next digit in our result. 
Result so far: 243836.0
If we take 2118 away from 2268, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 9:
1500 divided by 353 is 4 with a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 243836.4
If we take 1412 away from 1500, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 10:
The number 353 fits into 880 2 times, leaving a remainder of 174.
The number 2 becomes the next digit in our result. 
Result so far: 243836.42
If we take 706 away from 880, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 11:
The number 353 fits into 1740 4 times, leaving a remainder of 328.
Put 4 as the next digit of the answer. 
Result so far: 243836.424
Deduct 1412 from 1740 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 12:
353 goes into 3280 9 times with a remainder of 103.
The next digit of our result is 9. 
Result so far: 243836.4249
If we subtract 3177 from 3280, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 13:
The number 353 fits into 1030 2 times, leaving a remainder of 324.
Write down 2 as next digit of the result. 
Result so far: 243836.42492
If we subtract 706 from 1030, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 14:
If we divide 3240 by 353, we get 9 and a remainder of 63.
Record the quotient 9 as the next digit in the result. 
Result so far: 243836.424929
If we subtract 3177 from 3240, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 15:
353 can be fit into 630 1 times, resulting in a remainder of 277.
Record the quotient 1 as the next digit in the result. 
Result so far: 243836.4249291
If we subtract 353 from 630, we get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

On to step 16:
When dividing 2770 by 353, we get 7 with a remainder of 299.
Put 7 as the next digit of the answer. 
Result so far: 243836.42492917
Deduct 2471 from 2770 and we're left with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Our division results in 243836.42492917 with a remaining 2.99e-07.
