39895836 ÷ 485 
Our goal is to divide 39895836 by 485.

Step 1:
The number 485 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 485

Step 2:
The number 485 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 485

Moving on to step 3:
485 goes into 398 0 times with a remainder of 398.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 398 and we're left with 398.
Grab the next digit (9) from the dividend, add it to 398, then carry on: 3989 / 485

Going ahead to step 4:
485 can be fit into 3989 8 times, resulting in a remainder of 109.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 3880 from 3989 and we're left with 109.
Take the next digit (5) from the dividend and append it to 109, then repeat: 1095 / 485

Let's proceed to step 5:
If we divide 1095 by 485, we get 2 and a remainder of 125.
Put 2 as the next digit of the answer. 
Result so far: 82.0
If we take 970 away from 1095, we end up with 125.
Bring next digit (8) of the dividend behind the 125 and repeat the process: 1258 / 485

Advancing to step 6:
When dividing 1258 by 485, we get 2 with a remainder of 288.
Put 2 as the next digit of the answer. 
Result so far: 822.0
Deduct 970 from 1258 and we're left with 288.
Grab the next digit (3) from the dividend, add it to 288, then carry on: 2883 / 485

On to step 7:
485 can be fit into 2883 5 times, resulting in a remainder of 458.
The number 5 becomes the next digit in our result. 
Result so far: 8225.0
Subtracting 2425 from 2883 leaves us with 458.
Grab the next digit (6) from the dividend, add it to 458, then carry on: 4586 / 485

On to step 8:
If we divide 4586 by 485, we get 9 and a remainder of 221.
The number 9 becomes the next digit in our result. 
Result so far: 82259.0
If we take 4365 away from 4586, we end up with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Moving on to step 9:
485 goes into 2210 4 times with a remainder of 270.
The next digit of our result is 4. 
Result so far: 82259.4
The remainder is 270 after subtracting 1940 from 2210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 10:
If we divide 2700 by 485, we get 5 and a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 82259.45
Subtract 2425 from 2700 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 11:
The number 485 fits into 2750 5 times, leaving a remainder of 325.
The number 5 becomes the next digit in our result. 
Result so far: 82259.455
Subtracting 2425 from 2750 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

The final outcome is 82259.455, with a leftover of 0.0325.
