73921542 divided by 388 
The aim is to understand the frequency of 388 in 73921542.

Going ahead to step 1:
388 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 388

On to step 2:
If we divide 73 by 388, we get 0 and a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Grab the next digit (9) from the dividend, add it to 73, then carry on: 739 / 388

Advancing to step 3:
739 divided by 388 is 1 with a remainder of 351.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 388 from 739 and we're left with 351.
Bring next digit (2) of the dividend behind the 351 and repeat the process: 3512 / 388

On to step 4:
388 goes into 3512 9 times with a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 3492 from 3512 to get 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 388

Moving on to step 5:
388 goes into 201 0 times with a remainder of 201.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
The remainder is 201 after subtracting 0 from 201.
Take the next digit (5) from the dividend and append it to 201, then repeat: 2015 / 388

Step 6:
388 can be fit into 2015 5 times, resulting in a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 1905.0
If we take 1940 away from 2015, we end up with 75.
Take the next digit (4) from the dividend and append it to 75, then repeat: 754 / 388

On to step 7:
When dividing 754 by 388, we get 1 with a remainder of 366.
Record the quotient 1 as the next digit in the result. 
Result so far: 19051.0
Subtract 388 from 754 to get 366.
Append the next digit (2) from the dividend to 366 and continue with: 3662 / 388

Step 8:
388 goes into 3662 9 times with a remainder of 170.
The next digit of our result is 9. 
Result so far: 190519.0
Subtract 3492 from 3662 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 9:
388 can be fit into 1700 4 times, resulting in a remainder of 148.
Use 4 as the next digit of our solution. 
Result so far: 190519.4
The remainder is 148 after subtracting 1552 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 10:
388 can be fit into 1480 3 times, resulting in a remainder of 316.
Use 3 as the next digit of our solution. 
Result so far: 190519.43
Subtracting 1164 from 1480 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 11:
The number 388 fits into 3160 8 times, leaving a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 190519.438
Subtract 3104 from 3160 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
560 divided by 388 is 1 with a remainder of 172.
Record the quotient 1 as the next digit in the result. 
Result so far: 190519.4381
The remainder is 172 after subtracting 388 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 13:
388 can be fit into 1720 4 times, resulting in a remainder of 168.
Write down 4 as next digit of the result. 
Result so far: 190519.43814
If we take 1552 away from 1720, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 14:
When dividing 1680 by 388, we get 4 with a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 190519.438144
The remainder is 128 after subtracting 1552 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The quotient of the division is 190519.438144, and the remainder is 1.28e-05.
