39485252 ÷ 979 
Let's see how many times 979 fits into 39485252.

Moving on to step 1:
When dividing 3 by 979, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
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 / 979

Let's proceed to step 2:
979 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 979

Going ahead to step 3:
If we divide 394 by 979, we get 0 and a remainder of 394.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 394, we get 394.
Append the next digit (8) from the dividend to 394 and continue with: 3948 / 979

Step 4:
The number 979 fits into 3948 4 times, leaving a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 3916 from 3948 and we're left with 32.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 979

Let's proceed to step 5:
The number 979 fits into 325 0 times, leaving a remainder of 325.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtract 0 from 325 to get 325.
Grab the next digit (2) from the dividend, add it to 325, then carry on: 3252 / 979

Going ahead to step 6:
979 goes into 3252 3 times with a remainder of 315.
Write down 3 as next digit of the result. 
Result so far: 403.0
Deduct 2937 from 3252 and we're left with 315.
Bring next digit (5) of the dividend behind the 315 and repeat the process: 3155 / 979

Step 7:
The number 979 fits into 3155 3 times, leaving a remainder of 218.
The next digit of our result is 3. 
Result so far: 4033.0
Subtracting 2937 from 3155 leaves us with 218.
Bring next digit (2) of the dividend behind the 218 and repeat the process: 2182 / 979

Step 8:
If we divide 2182 by 979, we get 2 and a remainder of 224.
The next digit of our result is 2. 
Result so far: 40332.0
Deduct 1958 from 2182 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 9:
2240 divided by 979 is 2 with a remainder of 282.
Put 2 as the next digit of the answer. 
Result so far: 40332.2
Subtracting 1958 from 2240 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 10:
The number 979 fits into 2820 2 times, leaving a remainder of 862.
The next digit of our result is 2. 
Result so far: 40332.22
The remainder is 862 after subtracting 1958 from 2820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8620, and continue the process.

The quotient of the division is 40332.22, and the remainder is 0.862.
