42187550 divided by 989 
The aim is to understand the frequency of 989 in 42187550.

Moving on to step 1:
989 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 989

Going ahead to step 2:
The number 989 fits into 42 0 times, leaving a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 989

On to step 3:
If we divide 421 by 989, we get 0 and a remainder of 421.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 421 leaves us with 421.
Grab the next digit (8) from the dividend, add it to 421, then carry on: 4218 / 989

Going ahead to step 4:
989 can be fit into 4218 4 times, resulting in a remainder of 262.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 262 after subtracting 3956 from 4218.
Include the next digit (7) from the dividend after 262, then repeat: 2627 / 989

Going ahead to step 5:
The number 989 fits into 2627 2 times, leaving a remainder of 649.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Deduct 1978 from 2627 and we're left with 649.
Include the next digit (5) from the dividend after 649, then repeat: 6495 / 989

Moving on to step 6:
If we divide 6495 by 989, we get 6 and a remainder of 561.
Use 6 as the next digit of our solution. 
Result so far: 426.0
If we subtract 5934 from 6495, we get 561.
Append the next digit (5) from the dividend to 561 and continue with: 5615 / 989

Moving on to step 7:
If we divide 5615 by 989, we get 5 and a remainder of 670.
The next digit of our result is 5. 
Result so far: 4265.0
If we take 4945 away from 5615, we end up with 670.
Append the next digit (0) from the dividend to 670 and continue with: 6700 / 989

On to step 8:
989 goes into 6700 6 times with a remainder of 766.
The number 6 becomes the next digit in our result. 
Result so far: 42656.0
Deduct 5934 from 6700 and we're left with 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

Going ahead to step 9:
989 can be fit into 7660 7 times, resulting in a remainder of 737.
Record the quotient 7 as the next digit in the result. 
Result so far: 42656.7
If we subtract 6923 from 7660, we get 737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

Moving on to step 10:
7370 divided by 989 is 7 with a remainder of 447.
The next digit of our result is 7. 
Result so far: 42656.77
Deduct 6923 from 7370 and we're left with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

After the division, we end up with 42656.77 and a remainder of 0.447.
