We look at the division of 70025686 by 388 
The aim is to understand the frequency of 388 in 70025686.

Going ahead to step 1:
If we divide 7 by 388, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 388

Going ahead to step 2:
The number 388 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Grab the next digit (0) from the dividend, add it to 70, then carry on: 700 / 388

Advancing to step 3:
The number 388 fits into 700 1 times, leaving a remainder of 312.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 388 from 700 leaves us with 312.
Take the next digit (2) from the dividend and append it to 312, then repeat: 3122 / 388

Going ahead to step 4:
388 goes into 3122 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 3104 from 3122, we get 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 388

Advancing to step 5:
185 divided by 388 is 0 with a remainder of 185.
Put 0 as the next digit of the answer. 
Result so far: 180.0
Deduct 0 from 185 and we're left with 185.
Append the next digit (6) from the dividend to 185 and continue with: 1856 / 388

Step 6:
When dividing 1856 by 388, we get 4 with a remainder of 304.
Use 4 as the next digit of our solution. 
Result so far: 1804.0
The remainder is 304 after subtracting 1552 from 1856.
Grab the next digit (8) from the dividend, add it to 304, then carry on: 3048 / 388

Moving on to step 7:
If we divide 3048 by 388, we get 7 and a remainder of 332.
Write down 7 as next digit of the result. 
Result so far: 18047.0
The remainder is 332 after subtracting 2716 from 3048.
Bring next digit (6) of the dividend behind the 332 and repeat the process: 3326 / 388

Step 8:
388 goes into 3326 8 times with a remainder of 222.
The next digit of our result is 8. 
Result so far: 180478.0
Subtract 3104 from 3326 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Moving on to step 9:
If we divide 2220 by 388, we get 5 and a remainder of 280.
Use 5 as the next digit of our solution. 
Result so far: 180478.5
If we subtract 1940 from 2220, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 10:
2800 divided by 388 is 7 with a remainder of 84.
The number 7 becomes the next digit in our result. 
Result so far: 180478.57
Subtract 2716 from 2800 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 11:
When dividing 840 by 388, we get 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 180478.572
Deduct 776 from 840 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
640 divided by 388 is 1 with a remainder of 252.
Put 1 as the next digit of the answer. 
Result so far: 180478.5721
If we subtract 388 from 640, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 13:
If we divide 2520 by 388, we get 6 and a remainder of 192.
Record the quotient 6 as the next digit in the result. 
Result so far: 180478.57216
The remainder is 192 after subtracting 2328 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 14:
1920 divided by 388 is 4 with a remainder of 368.
Use 4 as the next digit of our solution. 
Result so far: 180478.572164
Subtract 1552 from 1920 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 15:
388 can be fit into 3680 9 times, resulting in a remainder of 188.
Record the quotient 9 as the next digit in the result. 
Result so far: 180478.5721649
Subtracting 3492 from 3680 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 16:
388 can be fit into 1880 4 times, resulting in a remainder of 328.
The next digit of our result is 4. 
Result so far: 180478.57216494
The remainder is 328 after subtracting 1552 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

The quotient of the division is 180478.57216494, and the remainder is 3.28e-07.
