Let's divide 90167619 by 378
The aim is to understand the frequency of 378 in 90167619.

Moving on to step 1:
When dividing 9 by 378, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 378

Going ahead to step 2:
378 can be fit into 90 0 times, resulting in a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Append the next digit (1) from the dividend to 90 and continue with: 901 / 378

Going ahead to step 3:
378 can be fit into 901 2 times, resulting in a remainder of 145.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 145 after subtracting 756 from 901.
Bring next digit (6) of the dividend behind the 145 and repeat the process: 1456 / 378

Advancing to step 4:
If we divide 1456 by 378, we get 3 and a remainder of 322.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
The remainder is 322 after subtracting 1134 from 1456.
Fetch the next digit (7) from the dividend, attach it to 322 and continue: 3227 / 378

Going ahead to step 5:
378 goes into 3227 8 times with a remainder of 203.
The next digit of our result is 8. 
Result so far: 238.0
Deduct 3024 from 3227 and we're left with 203.
Grab the next digit (6) from the dividend, add it to 203, then carry on: 2036 / 378

Going ahead to step 6:
378 can be fit into 2036 5 times, resulting in a remainder of 146.
Write down 5 as next digit of the result. 
Result so far: 2385.0
If we subtract 1890 from 2036, we get 146.
Bring next digit (1) of the dividend behind the 146 and repeat the process: 1461 / 378

On to step 7:
1461 divided by 378 is 3 with a remainder of 327.
Put 3 as the next digit of the answer. 
Result so far: 23853.0
Subtract 1134 from 1461 to get 327.
Include the next digit (9) from the dividend after 327, then repeat: 3279 / 378

On to step 8:
378 goes into 3279 8 times with a remainder of 255.
Use 8 as the next digit of our solution. 
Result so far: 238538.0
The remainder is 255 after subtracting 3024 from 3279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 9:
378 goes into 2550 6 times with a remainder of 282.
The number 6 becomes the next digit in our result. 
Result so far: 238538.6
Subtract 2268 from 2550 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 10:
2820 divided by 378 is 7 with a remainder of 174.
Record the quotient 7 as the next digit in the result. 
Result so far: 238538.67
If we take 2646 away from 2820, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 11:
1740 divided by 378 is 4 with a remainder of 228.
Put 4 as the next digit of the answer. 
Result so far: 238538.674
Subtract 1512 from 1740 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 12:
2280 divided by 378 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 238538.6746
If we subtract 2268 from 2280, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
120 divided by 378 is 0 with a remainder of 120.
The next digit of our result is 0. 
Result so far: 238538.6746
Subtract 0 from 120 to 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.

Moving on to step 14:
The number 378 fits into 1200 3 times, leaving a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 238538.674603
If we take 1134 away from 1200, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 15:
When dividing 660 by 378, we get 1 with a remainder of 282.
Put 1 as the next digit of the answer. 
Result so far: 238538.6746031
If we take 378 away from 660, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 16:
2820 divided by 378 is 7 with a remainder of 174.
Record the quotient 7 as the next digit in the result. 
Result so far: 238538.67460317
Deduct 2646 from 2820 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

In conclusion, the division gives 238538.67460317 with a balance of 1.74e-07.
