40615574 ÷ 987 
The aim is to understand the frequency of 987 in 40615574.

Going ahead to step 1:
4 divided by 987 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 987

Advancing to step 2:
40 divided by 987 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 987

On to step 3:
987 can be fit into 406 0 times, resulting in a remainder of 406.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 406 leaves us with 406.
Append the next digit (1) from the dividend to 406 and continue with: 4061 / 987

Step 4:
987 goes into 4061 4 times with a remainder of 113.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 3948 from 4061 to get 113.
Take the next digit (5) from the dividend and append it to 113, then repeat: 1135 / 987

Step 5:
987 goes into 1135 1 times with a remainder of 148.
Use 1 as the next digit of our solution. 
Result so far: 41.0
The remainder is 148 after subtracting 987 from 1135.
Take the next digit (5) from the dividend and append it to 148, then repeat: 1485 / 987

Going ahead to step 6:
987 goes into 1485 1 times with a remainder of 498.
Record the quotient 1 as the next digit in the result. 
Result so far: 411.0
The remainder is 498 after subtracting 987 from 1485.
Grab the next digit (7) from the dividend, add it to 498, then carry on: 4987 / 987

Step 7:
If we divide 4987 by 987, we get 5 and a remainder of 52.
Put 5 as the next digit of the answer. 
Result so far: 4115.0
Subtract 4935 from 4987 to get 52.
Append the next digit (4) from the dividend to 52 and continue with: 524 / 987

Step 8:
When dividing 524 by 987, we get 0 with a remainder of 524.
The number 0 becomes the next digit in our result. 
Result so far: 41150.0
Deduct 0 from 524 and we're left with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Let's proceed to step 9:
The number 987 fits into 5240 5 times, leaving a remainder of 305.
Record the quotient 5 as the next digit in the result. 
Result so far: 41150.5
Subtract 4935 from 5240 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 10:
987 goes into 3050 3 times with a remainder of 89.
Put 3 as the next digit of the answer. 
Result so far: 41150.53
Subtract 2961 from 3050 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 11:
The number 987 fits into 890 0 times, leaving a remainder of 890.
Put 0 as the next digit of the answer. 
Result so far: 41150.53
The remainder is 890 after subtracting 0 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

Moving on to step 12:
8900 divided by 987 is 9 with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 41150.5309
The remainder is 17 after subtracting 8883 from 8900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 13:
The number 987 fits into 170 0 times, leaving a remainder of 170.
The number 0 becomes the next digit in our result. 
Result so far: 41150.5309
If we subtract 0 from 170, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 14:
987 goes into 1700 1 times with a remainder of 713.
The next digit of our result is 1. 
Result so far: 41150.530901
Subtract 987 from 1700 to get 713.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7130, and continue the process.

Moving on to step 15:
If we divide 7130 by 987, we get 7 and a remainder of 221.
The next digit of our result is 7. 
Result so far: 41150.5309017
Subtract 6909 from 7130 to get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Step 16:
2210 divided by 987 is 2 with a remainder of 236.
The number 2 becomes the next digit in our result. 
Result so far: 41150.53090172
Subtracting 1974 from 2210 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The quotient of the division is 41150.53090172, and the remainder is 2.36e-07.
