7309958 divided by 616 
The aim is to understand the frequency of 616 in 7309958.

On to step 1:
616 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 616

Advancing to step 2:
616 can be fit into 73 0 times, resulting in a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Take the next digit (0) from the dividend and append it to 73, then repeat: 730 / 616

Step 3:
When dividing 730 by 616, we get 1 with a remainder of 114.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 616 away from 730, we end up with 114.
Bring next digit (9) of the dividend behind the 114 and repeat the process: 1149 / 616

Step 4:
If we divide 1149 by 616, we get 1 and a remainder of 533.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 616 from 1149 and we're left with 533.
Bring next digit (9) of the dividend behind the 533 and repeat the process: 5339 / 616

On to step 5:
616 can be fit into 5339 8 times, resulting in a remainder of 411.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
Deduct 4928 from 5339 and we're left with 411.
Append the next digit (5) from the dividend to 411 and continue with: 4115 / 616

On to step 6:
616 goes into 4115 6 times with a remainder of 419.
The next digit of our result is 6. 
Result so far: 1186.0
If we subtract 3696 from 4115, we get 419.
Include the next digit (8) from the dividend after 419, then repeat: 4198 / 616

On to step 7:
The number 616 fits into 4198 6 times, leaving a remainder of 502.
Use 6 as the next digit of our solution. 
Result so far: 11866.0
If we subtract 3696 from 4198, we get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Moving on to step 8:
616 goes into 5020 8 times with a remainder of 92.
The number 8 becomes the next digit in our result. 
Result so far: 11866.8
Subtract 4928 from 5020 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 9:
The number 616 fits into 920 1 times, leaving a remainder of 304.
The next digit of our result is 1. 
Result so far: 11866.81
If we take 616 away from 920, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 10:
If we divide 3040 by 616, we get 4 and a remainder of 576.
Record the quotient 4 as the next digit in the result. 
Result so far: 11866.814
Subtracting 2464 from 3040 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Moving on to step 11:
616 can be fit into 5760 9 times, resulting in a remainder of 216.
Put 9 as the next digit of the answer. 
Result so far: 11866.8149
Subtract 5544 from 5760 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 12:
2160 divided by 616 is 3 with a remainder of 312.
Put 3 as the next digit of the answer. 
Result so far: 11866.81493
If we subtract 1848 from 2160, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 13:
The number 616 fits into 3120 5 times, leaving a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 11866.814935
Deduct 3080 from 3120 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
616 goes into 400 0 times with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 11866.814935
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 15:
4000 divided by 616 is 6 with a remainder of 304.
Record the quotient 6 as the next digit in the result. 
Result so far: 11866.81493506
The remainder is 304 after subtracting 3696 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The final outcome is 11866.81493506, with a leftover of 3.04e-07.
