We're dividing 76341840 by 361 
The aim is to understand the frequency of 361 in 76341840.

Advancing to step 1:
The number 361 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 361

Let's proceed to step 2:
361 goes into 76 0 times with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Include the next digit (3) from the dividend after 76, then repeat: 763 / 361

Moving on to step 3:
The number 361 fits into 763 2 times, leaving a remainder of 41.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 722 from 763 and we're left with 41.
Append the next digit (4) from the dividend to 41 and continue with: 414 / 361

Advancing to step 4:
If we divide 414 by 361, we get 1 and a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 361 from 414, we get 53.
Append the next digit (1) from the dividend to 53 and continue with: 531 / 361

Step 5:
361 can be fit into 531 1 times, resulting in a remainder of 170.
Record the quotient 1 as the next digit in the result. 
Result so far: 211.0
Subtracting 361 from 531 leaves us with 170.
Bring next digit (8) of the dividend behind the 170 and repeat the process: 1708 / 361

Moving on to step 6:
1708 divided by 361 is 4 with a remainder of 264.
The next digit of our result is 4. 
Result so far: 2114.0
Deduct 1444 from 1708 and we're left with 264.
Bring next digit (4) of the dividend behind the 264 and repeat the process: 2644 / 361

Going ahead to step 7:
When dividing 2644 by 361, we get 7 with a remainder of 117.
Write down 7 as next digit of the result. 
Result so far: 21147.0
Subtracting 2527 from 2644 leaves us with 117.
Take the next digit (0) from the dividend and append it to 117, then repeat: 1170 / 361

Moving on to step 8:
361 can be fit into 1170 3 times, resulting in a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 211473.0
Subtracting 1083 from 1170 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 9:
The number 361 fits into 870 2 times, leaving a remainder of 148.
The number 2 becomes the next digit in our result. 
Result so far: 211473.2
If we subtract 722 from 870, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 10:
When dividing 1480 by 361, we get 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 211473.24
If we subtract 1444 from 1480, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
361 can be fit into 360 0 times, resulting in a remainder of 360.
The next digit of our result is 0. 
Result so far: 211473.24
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 12:
361 can be fit into 3600 9 times, resulting in a remainder of 351.
Use 9 as the next digit of our solution. 
Result so far: 211473.2409
Deduct 3249 from 3600 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Moving on to step 13:
When dividing 3510 by 361, we get 9 with a remainder of 261.
Write down 9 as next digit of the result. 
Result so far: 211473.24099
If we take 3249 away from 3510, we end up with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

The final outcome is 211473.24099, with a leftover of 0.000261.
