41723917 ÷ 987 
The aim is to understand the frequency of 987 in 41723917.

Let's proceed to step 1:
The number 987 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 987

Step 2:
41 divided by 987 is 0 with a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 41, we get 41.
Fetch the next digit (7) from the dividend, attach it to 41 and continue: 417 / 987

Going ahead to step 3:
987 goes into 417 0 times with a remainder of 417.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 417, we end up with 417.
Take the next digit (2) from the dividend and append it to 417, then repeat: 4172 / 987

Step 4:
4172 divided by 987 is 4 with a remainder of 224.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 3948 away from 4172, we end up with 224.
Grab the next digit (3) from the dividend, add it to 224, then carry on: 2243 / 987

Let's proceed to step 5:
When dividing 2243 by 987, we get 2 with a remainder of 269.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Deduct 1974 from 2243 and we're left with 269.
Grab the next digit (9) from the dividend, add it to 269, then carry on: 2699 / 987

Moving on to step 6:
If we divide 2699 by 987, we get 2 and a remainder of 725.
The number 2 becomes the next digit in our result. 
Result so far: 422.0
Subtracting 1974 from 2699 leaves us with 725.
Take the next digit (1) from the dividend and append it to 725, then repeat: 7251 / 987

On to step 7:
When dividing 7251 by 987, we get 7 with a remainder of 342.
Put 7 as the next digit of the answer. 
Result so far: 4227.0
The remainder is 342 after subtracting 6909 from 7251.
Append the next digit (7) from the dividend to 342 and continue with: 3427 / 987

On to step 8:
When dividing 3427 by 987, we get 3 with a remainder of 466.
Use 3 as the next digit of our solution. 
Result so far: 42273.0
If we take 2961 away from 3427, we end up with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Let's proceed to step 9:
4660 divided by 987 is 4 with a remainder of 712.
The next digit of our result is 4. 
Result so far: 42273.4
The remainder is 712 after subtracting 3948 from 4660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

On to step 10:
987 can be fit into 7120 7 times, resulting in a remainder of 211.
The next digit of our result is 7. 
Result so far: 42273.47
If we take 6909 away from 7120, we end up with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Moving on to step 11:
If we divide 2110 by 987, we get 2 and a remainder of 136.
Record the quotient 2 as the next digit in the result. 
Result so far: 42273.472
Subtract 1974 from 2110 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 12:
When dividing 1360 by 987, we get 1 with a remainder of 373.
Write down 1 as next digit of the result. 
Result so far: 42273.4721
Subtract 987 from 1360 to get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Let's proceed to step 13:
If we divide 3730 by 987, we get 3 and a remainder of 769.
Use 3 as the next digit of our solution. 
Result so far: 42273.47213
Deduct 2961 from 3730 and we're left with 769.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7690, and continue the process.

Moving on to step 14:
987 goes into 7690 7 times with a remainder of 781.
The next digit of our result is 7. 
Result so far: 42273.472137
If we subtract 6909 from 7690, we get 781.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7810, and continue the process.

Let's proceed to step 15:
987 can be fit into 7810 7 times, resulting in a remainder of 901.
Write down 7 as next digit of the result. 
Result so far: 42273.4721377
Subtract 6909 from 7810 to get 901.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9010, and continue the process.

The final result is 42273.4721377 with a remainder of 9.01e-06.
