We're dividing 90474448 by 361 
The aim is to understand the frequency of 361 in 90474448.

Going ahead to step 1:
If we divide 9 by 361, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 361

Moving on to step 2:
361 goes into 90 0 times with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Append the next digit (4) from the dividend to 90 and continue with: 904 / 361

Going ahead to step 3:
361 goes into 904 2 times with a remainder of 182.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 722 from 904 and we're left with 182.
Append the next digit (7) from the dividend to 182 and continue with: 1827 / 361

Advancing to step 4:
361 goes into 1827 5 times with a remainder of 22.
The next digit of our result is 5. 
Result so far: 25.0
Deduct 1805 from 1827 and we're left with 22.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 361

Step 5:
The number 361 fits into 224 0 times, leaving a remainder of 224.
Record the quotient 0 as the next digit in the result. 
Result so far: 250.0
If we subtract 0 from 224, we get 224.
Bring next digit (4) of the dividend behind the 224 and repeat the process: 2244 / 361

Advancing to step 6:
If we divide 2244 by 361, we get 6 and a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 2506.0
Subtracting 2166 from 2244 leaves us with 78.
Append the next digit (4) from the dividend to 78 and continue with: 784 / 361

Advancing to step 7:
784 divided by 361 is 2 with a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 25062.0
Subtract 722 from 784 to get 62.
Take the next digit (8) from the dividend and append it to 62, then repeat: 628 / 361

Going ahead to step 8:
361 can be fit into 628 1 times, resulting in a remainder of 267.
Record the quotient 1 as the next digit in the result. 
Result so far: 250621.0
Subtract 361 from 628 to get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Advancing to step 9:
2670 divided by 361 is 7 with a remainder of 143.
Put 7 as the next digit of the answer. 
Result so far: 250621.7
Subtract 2527 from 2670 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Going ahead to step 10:
The number 361 fits into 1430 3 times, leaving a remainder of 347.
The number 3 becomes the next digit in our result. 
Result so far: 250621.73
Subtract 1083 from 1430 to get 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Moving on to step 11:
3470 divided by 361 is 9 with a remainder of 221.
Use 9 as the next digit of our solution. 
Result so far: 250621.739
If we subtract 3249 from 3470, we get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Moving on to step 12:
When dividing 2210 by 361, we get 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 250621.7396
Subtracting 2166 from 2210 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
When dividing 440 by 361, we get 1 with a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 250621.73961
If we take 361 away from 440, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 14:
361 can be fit into 790 2 times, resulting in a remainder of 68.
The next digit of our result is 2. 
Result so far: 250621.739612
If we subtract 722 from 790, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 15:
When dividing 680 by 361, we get 1 with a remainder of 319.
Put 1 as the next digit of the answer. 
Result so far: 250621.7396121
Deduct 361 from 680 and we're left with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

On to step 16:
361 goes into 3190 8 times with a remainder of 302.
The next digit of our result is 8. 
Result so far: 250621.73961218
Deduct 2888 from 3190 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

After the division, we end up with 250621.73961218 and a remainder of 3.02e-07.
