903720 ÷ 61 
The aim is to understand the frequency of 61 in 903720.

On to step 1:
61 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 61

Advancing to step 2:
61 goes into 90 1 times with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 61 from 90 to get 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 61

Advancing to step 3:
61 can be fit into 293 4 times, resulting in a remainder of 49.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 244 from 293 leaves us with 49.
Bring next digit (7) of the dividend behind the 49 and repeat the process: 497 / 61

Step 4:
When dividing 497 by 61, we get 8 with a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 148.0
If we take 488 away from 497, we end up with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 61

Let's proceed to step 5:
The number 61 fits into 92 1 times, leaving a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1481.0
If we take 61 away from 92, we end up with 31.
Take the next digit (0) from the dividend and append it to 31, then repeat: 310 / 61

Let's proceed to step 6:
If we divide 310 by 61, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 14815.0
If we subtract 305 from 310, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
61 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 14815.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
500 divided by 61 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 14815.08
Deduct 488 from 500 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
The number 61 fits into 120 1 times, leaving a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 14815.081
Subtract 61 from 120 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 10:
61 goes into 590 9 times with a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 14815.0819
Deduct 549 from 590 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 11:
410 divided by 61 is 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 14815.08196
Subtracting 366 from 410 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 12:
The number 61 fits into 440 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 14815.081967
If we subtract 427 from 440, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 13:
130 divided by 61 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 14815.0819672
Subtract 122 from 130 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
61 can be fit into 80 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 14815.08196721
Deduct 61 from 80 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final result is 14815.08196721 with a remainder of 1.9e-08.
