39631660 ÷ 634 
The aim is to understand the frequency of 634 in 39631660.

Advancing to step 1:
634 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 634

Step 2:
The number 634 fits into 39 0 times, leaving a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 634

Step 3:
634 goes into 396 0 times with a remainder of 396.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 396, we end up with 396.
Bring next digit (3) of the dividend behind the 396 and repeat the process: 3963 / 634

Moving on to step 4:
If we divide 3963 by 634, we get 6 and a remainder of 159.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 3804 from 3963, we get 159.
Append the next digit (1) from the dividend to 159 and continue with: 1591 / 634

Advancing to step 5:
When dividing 1591 by 634, we get 2 with a remainder of 323.
Use 2 as the next digit of our solution. 
Result so far: 62.0
If we take 1268 away from 1591, we end up with 323.
Bring next digit (6) of the dividend behind the 323 and repeat the process: 3236 / 634

Advancing to step 6:
The number 634 fits into 3236 5 times, leaving a remainder of 66.
Write down 5 as next digit of the result. 
Result so far: 625.0
Subtracting 3170 from 3236 leaves us with 66.
Bring next digit (6) of the dividend behind the 66 and repeat the process: 666 / 634

Step 7:
666 divided by 634 is 1 with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 6251.0
If we subtract 634 from 666, we get 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 634

Advancing to step 8:
634 goes into 320 0 times with a remainder of 320.
The next digit of our result is 0. 
Result so far: 62510.0
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 9:
When dividing 3200 by 634, we get 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 62510.5
If we take 3170 away from 3200, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
When dividing 300 by 634, we get 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 62510.5
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 11:
The number 634 fits into 3000 4 times, leaving a remainder of 464.
Use 4 as the next digit of our solution. 
Result so far: 62510.504
The remainder is 464 after subtracting 2536 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

On to step 12:
634 can be fit into 4640 7 times, resulting in a remainder of 202.
Put 7 as the next digit of the answer. 
Result so far: 62510.5047
Subtract 4438 from 4640 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 13:
The number 634 fits into 2020 3 times, leaving a remainder of 118.
Write down 3 as next digit of the result. 
Result so far: 62510.50473
The remainder is 118 after subtracting 1902 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 14:
634 can be fit into 1180 1 times, resulting in a remainder of 546.
Put 1 as the next digit of the answer. 
Result so far: 62510.504731
If we take 634 away from 1180, we end up with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Let's proceed to step 15:
634 goes into 5460 8 times with a remainder of 388.
The number 8 becomes the next digit in our result. 
Result so far: 62510.5047318
The remainder is 388 after subtracting 5072 from 5460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Let's proceed to step 16:
When dividing 3880 by 634, we get 6 with a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 62510.50473186
Deduct 3804 from 3880 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 62510.50473186, with a leftover of 7.6e-08.
