73826658 ÷ 378 
The aim is to understand the frequency of 378 in 73826658.

Going ahead to step 1:
When dividing 7 by 378, 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 take 0 away from 7, we end up with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 378

Going ahead to step 2:
If we divide 73 by 378, we get 0 and a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Fetch the next digit (8) from the dividend, attach it to 73 and continue: 738 / 378

Step 3:
378 goes into 738 1 times with a remainder of 360.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 378 from 738 and we're left with 360.
Append the next digit (2) from the dividend to 360 and continue with: 3602 / 378

Advancing to step 4:
If we divide 3602 by 378, we get 9 and a remainder of 200.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 3402 away from 3602, we end up with 200.
Fetch the next digit (6) from the dividend, attach it to 200 and continue: 2006 / 378

Step 5:
If we divide 2006 by 378, we get 5 and a remainder of 116.
Use 5 as the next digit of our solution. 
Result so far: 195.0
If we subtract 1890 from 2006, we get 116.
Grab the next digit (6) from the dividend, add it to 116, then carry on: 1166 / 378

Going ahead to step 6:
The number 378 fits into 1166 3 times, leaving a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 1953.0
Deduct 1134 from 1166 and we're left with 32.
Include the next digit (5) from the dividend after 32, then repeat: 325 / 378

Let's proceed to step 7:
When dividing 325 by 378, we get 0 with a remainder of 325.
The next digit of our result is 0. 
Result so far: 19530.0
Subtracting 0 from 325 leaves us with 325.
Fetch the next digit (8) from the dividend, attach it to 325 and continue: 3258 / 378

Advancing to step 8:
When dividing 3258 by 378, we get 8 with a remainder of 234.
Write down 8 as next digit of the result. 
Result so far: 195308.0
Subtracting 3024 from 3258 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 9:
2340 divided by 378 is 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 195308.6
If we subtract 2268 from 2340, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 10:
The number 378 fits into 720 1 times, leaving a remainder of 342.
Use 1 as the next digit of our solution. 
Result so far: 195308.61
The remainder is 342 after subtracting 378 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Moving on to step 11:
The number 378 fits into 3420 9 times, leaving a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 195308.619
The remainder is 18 after subtracting 3402 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
The number 378 fits into 180 0 times, leaving a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 195308.619
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 13:
The number 378 fits into 1800 4 times, leaving a remainder of 288.
Put 4 as the next digit of the answer. 
Result so far: 195308.61904
Subtracting 1512 from 1800 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 14:
The number 378 fits into 2880 7 times, leaving a remainder of 234.
The number 7 becomes the next digit in our result. 
Result so far: 195308.619047
Subtract 2646 from 2880 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 15:
The number 378 fits into 2340 6 times, leaving a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 195308.6190476
If we subtract 2268 from 2340, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 16:
When dividing 720 by 378, we get 1 with a remainder of 342.
The number 1 becomes the next digit in our result. 
Result so far: 195308.61904761
If we take 378 away from 720, we end up with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

The final outcome is 195308.61904761, with a leftover of 3.42e-07.
