Let's divide 87021915 by 937
The aim is to understand the frequency of 937 in 87021915.

Step 1:
937 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 937

Going ahead to step 2:
The number 937 fits into 87 0 times, leaving a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Append the next digit (0) from the dividend to 87 and continue with: 870 / 937

Step 3:
If we divide 870 by 937, we get 0 and a remainder of 870.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 870, we get 870.
Bring next digit (2) of the dividend behind the 870 and repeat the process: 8702 / 937

Moving on to step 4:
937 can be fit into 8702 9 times, resulting in a remainder of 269.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 8433 from 8702 leaves us with 269.
Take the next digit (1) from the dividend and append it to 269, then repeat: 2691 / 937

Let's proceed to step 5:
If we divide 2691 by 937, we get 2 and a remainder of 817.
The next digit of our result is 2. 
Result so far: 92.0
If we subtract 1874 from 2691, we get 817.
Bring next digit (9) of the dividend behind the 817 and repeat the process: 8179 / 937

Let's proceed to step 6:
8179 divided by 937 is 8 with a remainder of 683.
Use 8 as the next digit of our solution. 
Result so far: 928.0
Subtract 7496 from 8179 to get 683.
Bring next digit (1) of the dividend behind the 683 and repeat the process: 6831 / 937

On to step 7:
If we divide 6831 by 937, we get 7 and a remainder of 272.
Put 7 as the next digit of the answer. 
Result so far: 9287.0
The remainder is 272 after subtracting 6559 from 6831.
Bring next digit (5) of the dividend behind the 272 and repeat the process: 2725 / 937

Advancing to step 8:
937 goes into 2725 2 times with a remainder of 851.
Write down 2 as next digit of the result. 
Result so far: 92872.0
The remainder is 851 after subtracting 1874 from 2725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8510, and continue the process.

Going ahead to step 9:
937 can be fit into 8510 9 times, resulting in a remainder of 77.
Use 9 as the next digit of our solution. 
Result so far: 92872.9
If we subtract 8433 from 8510, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 10:
937 goes into 770 0 times with a remainder of 770.
Put 0 as the next digit of the answer. 
Result so far: 92872.9
The remainder is 770 after subtracting 0 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Going ahead to step 11:
937 goes into 7700 8 times with a remainder of 204.
Put 8 as the next digit of the answer. 
Result so far: 92872.908
If we subtract 7496 from 7700, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 12:
937 can be fit into 2040 2 times, resulting in a remainder of 166.
Use 2 as the next digit of our solution. 
Result so far: 92872.9082
Subtracting 1874 from 2040 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 13:
937 can be fit into 1660 1 times, resulting in a remainder of 723.
Write down 1 as next digit of the result. 
Result so far: 92872.90821
If we take 937 away from 1660, we end up with 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Let's proceed to step 14:
937 goes into 7230 7 times with a remainder of 671.
The number 7 becomes the next digit in our result. 
Result so far: 92872.908217
If we subtract 6559 from 7230, we get 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

Let's proceed to step 15:
6710 divided by 937 is 7 with a remainder of 151.
Use 7 as the next digit of our solution. 
Result so far: 92872.9082177
Deduct 6559 from 6710 and we're left with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

In conclusion, the division gives 92872.9082177 with a balance of 1.51e-06.
