637174 divided by 61 
The aim is to understand the frequency of 61 in 637174.

On to step 1:
The number 61 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 61

Let's proceed to step 2:
When dividing 63 by 61, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 61 from 63 and we're left with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 61

On to step 3:
61 can be fit into 27 0 times, resulting in a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 27, we end up with 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 61

Moving on to step 4:
If we divide 271 by 61, we get 4 and a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Subtract 244 from 271 to get 27.
Grab the next digit (7) from the dividend, add it to 27, then carry on: 277 / 61

Step 5:
The number 61 fits into 277 4 times, leaving a remainder of 33.
Write down 4 as next digit of the result. 
Result so far: 1044.0
If we take 244 away from 277, we end up with 33.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 61

Moving on to step 6:
61 can be fit into 334 5 times, resulting in a remainder of 29.
Use 5 as the next digit of our solution. 
Result so far: 10445.0
If we subtract 305 from 334, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
61 goes into 290 4 times with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 10445.4
Subtract 244 from 290 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 8:
61 goes into 460 7 times with a remainder of 33.
The next digit of our result is 7. 
Result so far: 10445.47
If we subtract 427 from 460, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 9:
330 divided by 61 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 10445.475
Subtract 305 from 330 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
250 divided by 61 is 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 10445.4754
Deduct 244 from 250 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
61 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 10445.4754
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
61 goes into 600 9 times with a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 10445.475409
If we subtract 549 from 600, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 13:
The number 61 fits into 510 8 times, leaving a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 10445.4754098
If we subtract 488 from 510, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
When dividing 220 by 61, we get 3 with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 10445.47540983
Subtract 183 from 220 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final result is 10445.47540983 with a remainder of 3.7e-08.
