357886 ÷ 86 
We want to figure out the number of times 357886 can be divided by 86.

Going ahead to step 1:
If we divide 3 by 86, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 86

Advancing to step 2:
When dividing 35 by 86, we get 0 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 (7) from the dividend to 35 and continue with: 357 / 86

Moving on to step 3:
86 goes into 357 4 times with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 344 away from 357, we end up with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 86

Moving on to step 4:
If we divide 138 by 86, we get 1 and a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Subtract 86 from 138 to get 52.
Include the next digit (8) from the dividend after 52, then repeat: 528 / 86

Moving on to step 5:
528 divided by 86 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 416.0
Subtract 516 from 528 to get 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 86

Step 6:
86 goes into 126 1 times with a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 4161.0
If we subtract 86 from 126, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
The number 86 fits into 400 4 times, leaving a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 4161.4
If we take 344 away from 400, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 8:
If we divide 560 by 86, we get 6 and a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 4161.46
If we take 516 away from 560, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
If we divide 440 by 86, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 4161.465
Subtracting 430 from 440 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
When dividing 100 by 86, we get 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 4161.4651
Subtract 86 from 100 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
When dividing 140 by 86, we get 1 with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 4161.46511
Subtracting 86 from 140 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 4161.46511 with a remaining 5.4e-05.
