73911742 divided by 615 
The aim is to understand the frequency of 615 in 73911742.

Going ahead to step 1:
When dividing 7 by 615, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 615

Step 2:
If we divide 73 by 615, we get 0 and a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Append the next digit (9) from the dividend to 73 and continue with: 739 / 615

Let's proceed to step 3:
739 divided by 615 is 1 with a remainder of 124.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 615 from 739 and we're left with 124.
Bring next digit (1) of the dividend behind the 124 and repeat the process: 1241 / 615

Step 4:
1241 divided by 615 is 2 with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 11 after subtracting 1230 from 1241.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 615

Step 5:
When dividing 111 by 615, we get 0 with a remainder of 111.
Write down 0 as next digit of the result. 
Result so far: 120.0
If we take 0 away from 111, we end up with 111.
Take the next digit (7) from the dividend and append it to 111, then repeat: 1117 / 615

On to step 6:
615 goes into 1117 1 times with a remainder of 502.
Record the quotient 1 as the next digit in the result. 
Result so far: 1201.0
If we take 615 away from 1117, we end up with 502.
Append the next digit (4) from the dividend to 502 and continue with: 5024 / 615

On to step 7:
615 can be fit into 5024 8 times, resulting in a remainder of 104.
Use 8 as the next digit of our solution. 
Result so far: 12018.0
If we subtract 4920 from 5024, we get 104.
Take the next digit (2) from the dividend and append it to 104, then repeat: 1042 / 615

Advancing to step 8:
The number 615 fits into 1042 1 times, leaving a remainder of 427.
Record the quotient 1 as the next digit in the result. 
Result so far: 120181.0
Deduct 615 from 1042 and we're left with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Let's proceed to step 9:
615 goes into 4270 6 times with a remainder of 580.
The number 6 becomes the next digit in our result. 
Result so far: 120181.6
Deduct 3690 from 4270 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 10:
When dividing 5800 by 615, we get 9 with a remainder of 265.
Put 9 as the next digit of the answer. 
Result so far: 120181.69
If we subtract 5535 from 5800, we get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 11:
615 goes into 2650 4 times with a remainder of 190.
Write down 4 as next digit of the result. 
Result so far: 120181.694
Subtract 2460 from 2650 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 12:
615 goes into 1900 3 times with a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 120181.6943
The remainder is 55 after subtracting 1845 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 13:
550 divided by 615 is 0 with a remainder of 550.
Record the quotient 0 as the next digit in the result. 
Result so far: 120181.6943
If we take 0 away from 550, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 14:
If we divide 5500 by 615, we get 8 and a remainder of 580.
Record the quotient 8 as the next digit in the result. 
Result so far: 120181.694308
If we take 4920 away from 5500, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 15:
615 can be fit into 5800 9 times, resulting in a remainder of 265.
Put 9 as the next digit of the answer. 
Result so far: 120181.6943089
If we take 5535 away from 5800, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 16:
615 can be fit into 2650 4 times, resulting in a remainder of 190.
Write down 4 as next digit of the result. 
Result so far: 120181.69430894
If we take 2460 away from 2650, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The final outcome is 120181.69430894, with a leftover of 1.9e-07.
