We divide 70819263 by 378
The aim is to understand the frequency of 378 in 70819263.

On to step 1:
378 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 378

Advancing to step 2:
378 goes into 70 0 times with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Include the next digit (8) from the dividend after 70, then repeat: 708 / 378

Let's proceed to step 3:
If we divide 708 by 378, we get 1 and a remainder of 330.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 378 from 708 to get 330.
Bring next digit (1) of the dividend behind the 330 and repeat the process: 3301 / 378

Moving on to step 4:
378 goes into 3301 8 times with a remainder of 277.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 3024 from 3301 to get 277.
Append the next digit (9) from the dividend to 277 and continue with: 2779 / 378

Going ahead to step 5:
378 can be fit into 2779 7 times, resulting in a remainder of 133.
The number 7 becomes the next digit in our result. 
Result so far: 187.0
The remainder is 133 after subtracting 2646 from 2779.
Take the next digit (2) from the dividend and append it to 133, then repeat: 1332 / 378

Moving on to step 6:
378 can be fit into 1332 3 times, resulting in a remainder of 198.
Put 3 as the next digit of the answer. 
Result so far: 1873.0
Subtract 1134 from 1332 to get 198.
Grab the next digit (6) from the dividend, add it to 198, then carry on: 1986 / 378

Moving on to step 7:
The number 378 fits into 1986 5 times, leaving a remainder of 96.
Write down 5 as next digit of the result. 
Result so far: 18735.0
If we subtract 1890 from 1986, we get 96.
Fetch the next digit (3) from the dividend, attach it to 96 and continue: 963 / 378

Step 8:
If we divide 963 by 378, we get 2 and a remainder of 207.
The next digit of our result is 2. 
Result so far: 187352.0
Deduct 756 from 963 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 9:
When dividing 2070 by 378, we get 5 with a remainder of 180.
The number 5 becomes the next digit in our result. 
Result so far: 187352.5
If we subtract 1890 from 2070, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 10:
The number 378 fits into 1800 4 times, leaving a remainder of 288.
Record the quotient 4 as the next digit in the result. 
Result so far: 187352.54
The remainder is 288 after subtracting 1512 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 11:
2880 divided by 378 is 7 with a remainder of 234.
Write down 7 as next digit of the result. 
Result so far: 187352.547
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.

Step 12:
2340 divided by 378 is 6 with a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 187352.5476
If we take 2268 away from 2340, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
720 divided by 378 is 1 with a remainder of 342.
The next digit of our result is 1. 
Result so far: 187352.54761
If we subtract 378 from 720, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Let's proceed to step 14:
3420 divided by 378 is 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 187352.547619
Deduct 3402 from 3420 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 15:
180 divided by 378 is 0 with a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 187352.547619
Subtracting 0 from 180 leaves us 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.

On to step 16:
378 goes into 1800 4 times with a remainder of 288.
Put 4 as the next digit of the answer. 
Result so far: 187352.54761904
Subtract 1512 from 1800 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 187352.54761904, with a leftover of 2.88e-07.
