83908474 ÷ 616 
The aim is to understand the frequency of 616 in 83908474.

Advancing to step 1:
When dividing 8 by 616, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 616

Advancing to step 2:
The number 616 fits into 83 0 times, leaving a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Grab the next digit (9) from the dividend, add it to 83, then carry on: 839 / 616

Step 3:
616 can be fit into 839 1 times, resulting in a remainder of 223.
The next digit of our result is 1. 
Result so far: 1.0
If we take 616 away from 839, we end up with 223.
Include the next digit (0) from the dividend after 223, then repeat: 2230 / 616

Step 4:
The number 616 fits into 2230 3 times, leaving a remainder of 382.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 1848 away from 2230, we end up with 382.
Include the next digit (8) from the dividend after 382, then repeat: 3828 / 616

Advancing to step 5:
The number 616 fits into 3828 6 times, leaving a remainder of 132.
The number 6 becomes the next digit in our result. 
Result so far: 136.0
Subtract 3696 from 3828 to get 132.
Grab the next digit (4) from the dividend, add it to 132, then carry on: 1324 / 616

Let's proceed to step 6:
The number 616 fits into 1324 2 times, leaving a remainder of 92.
The number 2 becomes the next digit in our result. 
Result so far: 1362.0
Subtracting 1232 from 1324 leaves us with 92.
Bring next digit (7) of the dividend behind the 92 and repeat the process: 927 / 616

Advancing to step 7:
616 goes into 927 1 times with a remainder of 311.
Put 1 as the next digit of the answer. 
Result so far: 13621.0
Subtract 616 from 927 to get 311.
Append the next digit (4) from the dividend to 311 and continue with: 3114 / 616

Moving on to step 8:
3114 divided by 616 is 5 with a remainder of 34.
Use 5 as the next digit of our solution. 
Result so far: 136215.0
Deduct 3080 from 3114 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
The number 616 fits into 340 0 times, leaving a remainder of 340.
Put 0 as the next digit of the answer. 
Result so far: 136215.0
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 10:
3400 divided by 616 is 5 with a remainder of 320.
Record the quotient 5 as the next digit in the result. 
Result so far: 136215.05
The remainder is 320 after subtracting 3080 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 11:
When dividing 3200 by 616, we get 5 with a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 136215.055
If we subtract 3080 from 3200, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The quotient of the division is 136215.055, and the remainder is 0.012.
