357911 divided by 86 
We're looking to find how many times 86 goes into 357911.

Step 1:
When dividing 3 by 86, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 86

On to step 2:
When dividing 35 by 86, we get 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Fetch the next digit (7) from the dividend, attach it to 35 and continue: 357 / 86

Moving on to step 3:
If we divide 357 by 86, we get 4 and a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 344 away from 357, we end up with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 86

Moving on to step 4:
The number 86 fits into 139 1 times, leaving a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 41.0
If we subtract 86 from 139, we get 53.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 86

Moving on to step 5:
When dividing 531 by 86, we get 6 with a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 416.0
If we subtract 516 from 531, we get 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 86

On to step 6:
If we divide 151 by 86, we get 1 and a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 4161.0
Deduct 86 from 151 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 7:
650 divided by 86 is 7 with a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 4161.7
Deduct 602 from 650 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 8:
480 divided by 86 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 4161.75
The remainder is 50 after subtracting 430 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
86 can be fit into 500 5 times, resulting in a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 4161.755
Deduct 430 from 500 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 4161.755, and the remainder is 0.007.
