We're dividing 63630237 by 731 
The aim is to understand the frequency of 731 in 63630237.

On to step 1:
The number 731 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 731

Moving on to step 2:
When dividing 63 by 731, we get 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Grab the next digit (6) from the dividend, add it to 63, then carry on: 636 / 731

On to step 3:
If we divide 636 by 731, we get 0 and a remainder of 636.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 636 and we're left with 636.
Bring next digit (3) of the dividend behind the 636 and repeat the process: 6363 / 731

Going ahead to step 4:
The number 731 fits into 6363 8 times, leaving a remainder of 515.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 5848 from 6363 to get 515.
Grab the next digit (0) from the dividend, add it to 515, then carry on: 5150 / 731

On to step 5:
If we divide 5150 by 731, we get 7 and a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 87.0
If we take 5117 away from 5150, we end up with 33.
Take the next digit (2) from the dividend and append it to 33, then repeat: 332 / 731

Advancing to step 6:
731 can be fit into 332 0 times, resulting in a remainder of 332.
The number 0 becomes the next digit in our result. 
Result so far: 870.0
If we subtract 0 from 332, we get 332.
Include the next digit (3) from the dividend after 332, then repeat: 3323 / 731

Moving on to step 7:
731 can be fit into 3323 4 times, resulting in a remainder of 399.
Write down 4 as next digit of the result. 
Result so far: 8704.0
If we subtract 2924 from 3323, we get 399.
Grab the next digit (7) from the dividend, add it to 399, then carry on: 3997 / 731

On to step 8:
3997 divided by 731 is 5 with a remainder of 342.
Record the quotient 5 as the next digit in the result. 
Result so far: 87045.0
The remainder is 342 after subtracting 3655 from 3997.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 9:
731 can be fit into 3420 4 times, resulting in a remainder of 496.
The number 4 becomes the next digit in our result. 
Result so far: 87045.4
Subtract 2924 from 3420 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

On to step 10:
4960 divided by 731 is 6 with a remainder of 574.
Record the quotient 6 as the next digit in the result. 
Result so far: 87045.46
Subtract 4386 from 4960 to get 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Going ahead to step 11:
The number 731 fits into 5740 7 times, leaving a remainder of 623.
The number 7 becomes the next digit in our result. 
Result so far: 87045.467
Subtract 5117 from 5740 to get 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

On to step 12:
731 can be fit into 6230 8 times, resulting in a remainder of 382.
Write down 8 as next digit of the result. 
Result so far: 87045.4678
If we take 5848 away from 6230, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Let's proceed to step 13:
When dividing 3820 by 731, we get 5 with a remainder of 165.
The number 5 becomes the next digit in our result. 
Result so far: 87045.46785
The remainder is 165 after subtracting 3655 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 14:
731 can be fit into 1650 2 times, resulting in a remainder of 188.
The number 2 becomes the next digit in our result. 
Result so far: 87045.467852
If we take 1462 away from 1650, we end up 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.

On to step 15:
If we divide 1880 by 731, we get 2 and a remainder of 418.
Write down 2 as next digit of the result. 
Result so far: 87045.4678522
If we subtract 1462 from 1880, we get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

In conclusion, the division gives 87045.4678522 with a balance of 4.18e-06.
