We divide 421705 by 85
We're looking to find how many times 85 goes into 421705.

On to step 1:
4 divided by 85 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 85

Advancing to step 2:
85 goes into 42 0 times with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 85

On to step 3:
When dividing 421 by 85, we get 4 with a remainder of 81.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 340 from 421 to get 81.
Bring next digit (7) of the dividend behind the 81 and repeat the process: 817 / 85

On to step 4:
85 goes into 817 9 times with a remainder of 52.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtract 765 from 817 to get 52.
Bring next digit (0) of the dividend behind the 52 and repeat the process: 520 / 85

Going ahead to step 5:
If we divide 520 by 85, we get 6 and a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 496.0
Deduct 510 from 520 and we're left with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 85

Moving on to step 6:
When dividing 105 by 85, we get 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 4961.0
Subtract 85 from 105 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
When dividing 200 by 85, we get 2 with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 4961.2
Subtracting 170 from 200 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
85 goes into 300 3 times with a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 4961.23
The remainder is 45 after subtracting 255 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 9:
The number 85 fits into 450 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 4961.235
Subtract 425 from 450 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
The number 85 fits into 250 2 times, leaving a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 4961.2352
Deduct 170 from 250 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
85 goes into 800 9 times with a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 4961.23529
If we subtract 765 from 800, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 12:
350 divided by 85 is 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 4961.235294
Deduct 340 from 350 and we're left 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.

Let's proceed to step 13:
85 goes into 100 1 times with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 4961.2352941
If we subtract 85 from 100, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
85 goes into 150 1 times with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 4961.23529411
Subtracting 85 from 150 leaves us 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.

The quotient of the division is 4961.23529411, and the remainder is 6.5e-08.
