436670 divided by 86 
We want to figure out the number of times 436670 can be divided by 86.

Advancing to step 1:
When dividing 4 by 86, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 86

On to step 2:
The number 86 fits into 43 0 times, leaving a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 86

Going ahead to step 3:
The number 86 fits into 436 5 times, leaving a remainder of 6.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 430 from 436 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 86

Going ahead to step 4:
If we divide 66 by 86, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 50.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (7) from the dividend to 66 and continue with: 667 / 86

Going ahead to step 5:
667 divided by 86 is 7 with a remainder of 65.
Write down 7 as next digit of the result. 
Result so far: 507.0
Subtract 602 from 667 to get 65.
Take the next digit (0) from the dividend and append it to 65, then repeat: 650 / 86

Advancing to step 6:
The number 86 fits into 650 7 times, leaving a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 5077.0
If we take 602 away from 650, we end up 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 7:
When dividing 480 by 86, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 5077.5
Subtracting 430 from 480 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
If we divide 500 by 86, we get 5 and a remainder of 70.
The next digit of our result is 5. 
Result so far: 5077.55
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.

Our division results in 5077.55 with a remaining 0.07.
