39493973 ÷ 616 
The aim is to understand the frequency of 616 in 39493973.

Going ahead to step 1:
3 divided by 616 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 616

On to step 2:
39 divided by 616 is 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 616

Let's proceed to step 3:
If we divide 394 by 616, we get 0 and a remainder of 394.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 394, we get 394.
Append the next digit (9) from the dividend to 394 and continue with: 3949 / 616

Advancing to step 4:
616 goes into 3949 6 times with a remainder of 253.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 3696 from 3949, we get 253.
Take the next digit (3) from the dividend and append it to 253, then repeat: 2533 / 616

Moving on to step 5:
616 can be fit into 2533 4 times, resulting in a remainder of 69.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Deduct 2464 from 2533 and we're left with 69.
Bring next digit (9) of the dividend behind the 69 and repeat the process: 699 / 616

Moving on to step 6:
If we divide 699 by 616, we get 1 and a remainder of 83.
The number 1 becomes the next digit in our result. 
Result so far: 641.0
Subtract 616 from 699 to get 83.
Include the next digit (7) from the dividend after 83, then repeat: 837 / 616

Going ahead to step 7:
If we divide 837 by 616, we get 1 and a remainder of 221.
Use 1 as the next digit of our solution. 
Result so far: 6411.0
Subtract 616 from 837 to get 221.
Grab the next digit (3) from the dividend, add it to 221, then carry on: 2213 / 616

Advancing to step 8:
When dividing 2213 by 616, we get 3 with a remainder of 365.
Put 3 as the next digit of the answer. 
Result so far: 64113.0
Subtract 1848 from 2213 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 9:
If we divide 3650 by 616, we get 5 and a remainder of 570.
Put 5 as the next digit of the answer. 
Result so far: 64113.5
If we subtract 3080 from 3650, we get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 10:
616 can be fit into 5700 9 times, resulting in a remainder of 156.
Use 9 as the next digit of our solution. 
Result so far: 64113.59
The remainder is 156 after subtracting 5544 from 5700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 11:
616 goes into 1560 2 times with a remainder of 328.
Put 2 as the next digit of the answer. 
Result so far: 64113.592
If we subtract 1232 from 1560, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 12:
When dividing 3280 by 616, we get 5 with a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 64113.5925
The remainder is 200 after subtracting 3080 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 13:
When dividing 2000 by 616, we get 3 with a remainder of 152.
Put 3 as the next digit of the answer. 
Result so far: 64113.59253
Subtracting 1848 from 2000 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 14:
616 can be fit into 1520 2 times, resulting in a remainder of 288.
Use 2 as the next digit of our solution. 
Result so far: 64113.592532
If we take 1232 away from 1520, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 15:
The number 616 fits into 2880 4 times, leaving a remainder of 416.
Use 4 as the next digit of our solution. 
Result so far: 64113.5925324
Subtract 2464 from 2880 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 16:
If we divide 4160 by 616, we get 6 and a remainder of 464.
The number 6 becomes the next digit in our result. 
Result so far: 64113.59253246
If we subtract 3696 from 4160, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

In conclusion, the division gives 64113.59253246 with a balance of 4.64e-07.
