We're dividing 6243866 by 989 
The aim is to understand the frequency of 989 in 6243866.

Let's proceed to step 1:
When dividing 6 by 989, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 989

On to step 2:
989 goes into 62 0 times with a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Fetch the next digit (4) from the dividend, attach it to 62 and continue: 624 / 989

Step 3:
If we divide 624 by 989, we get 0 and a remainder of 624.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 624 after subtracting 0 from 624.
Take the next digit (3) from the dividend and append it to 624, then repeat: 6243 / 989

Step 4:
989 goes into 6243 6 times with a remainder of 309.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 5934 from 6243 to get 309.
Append the next digit (8) from the dividend to 309 and continue with: 3098 / 989

Moving on to step 5:
If we divide 3098 by 989, we get 3 and a remainder of 131.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtract 2967 from 3098 to get 131.
Fetch the next digit (6) from the dividend, attach it to 131 and continue: 1316 / 989

Step 6:
When dividing 1316 by 989, we get 1 with a remainder of 327.
The next digit of our result is 1. 
Result so far: 631.0
The remainder is 327 after subtracting 989 from 1316.
Grab the next digit (6) from the dividend, add it to 327, then carry on: 3276 / 989

Let's proceed to step 7:
989 can be fit into 3276 3 times, resulting in a remainder of 309.
Record the quotient 3 as the next digit in the result. 
Result so far: 6313.0
If we subtract 2967 from 3276, we get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Moving on to step 8:
989 goes into 3090 3 times with a remainder of 123.
Use 3 as the next digit of our solution. 
Result so far: 6313.3
If we take 2967 away from 3090, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 9:
When dividing 1230 by 989, we get 1 with a remainder of 241.
Put 1 as the next digit of the answer. 
Result so far: 6313.31
The remainder is 241 after subtracting 989 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Step 10:
989 goes into 2410 2 times with a remainder of 432.
Write down 2 as next digit of the result. 
Result so far: 6313.312
If we subtract 1978 from 2410, we get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 11:
When dividing 4320 by 989, we get 4 with a remainder of 364.
Record the quotient 4 as the next digit in the result. 
Result so far: 6313.3124
If we take 3956 away from 4320, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 12:
If we divide 3640 by 989, we get 3 and a remainder of 673.
Use 3 as the next digit of our solution. 
Result so far: 6313.31243
If we take 2967 away from 3640, we end up with 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6730, and continue the process.

Going ahead to step 13:
6730 divided by 989 is 6 with a remainder of 796.
Record the quotient 6 as the next digit in the result. 
Result so far: 6313.312436
The remainder is 796 after subtracting 5934 from 6730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Advancing to step 14:
989 goes into 7960 8 times with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 6313.3124368
If we take 7912 away from 7960, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 15:
989 can be fit into 480 0 times, resulting in a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 6313.3124368
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

After the division, we end up with 6313.3124368 and a remainder of 4.8e-07.
