987699 ÷ 50 
The aim is to understand the frequency of 50 in 987699.

Moving on to step 1:
When dividing 9 by 50, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 50

Moving on to step 2:
The number 50 fits into 98 1 times, leaving a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 50 from 98 and we're left with 48.
Take the next digit (7) from the dividend and append it to 48, then repeat: 487 / 50

Advancing to step 3:
The number 50 fits into 487 9 times, leaving a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 450 from 487 to get 37.
Grab the next digit (6) from the dividend, add it to 37, then carry on: 376 / 50

On to step 4:
50 goes into 376 7 times with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 197.0
If we take 350 away from 376, we end up with 26.
Bring next digit (9) of the dividend behind the 26 and repeat the process: 269 / 50

On to step 5:
If we divide 269 by 50, we get 5 and a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 1975.0
If we take 250 away from 269, we end up with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 50

Moving on to step 6:
When dividing 199 by 50, we get 3 with a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 19753.0
Deduct 150 from 199 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
The number 50 fits into 490 9 times, leaving a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 19753.9
Deduct 450 from 490 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
400 divided by 50 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 19753.98
Subtracting 400 from 400 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
0 divided by 50 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 19753.98
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
0 divided by 50 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 19753.98
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 19753.98 with a remaining 0.0.
