Let's divide 16131400 by 87
The aim is to understand the frequency of 87 in 16131400.

Step 1:
1 divided by 87 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 87

Step 2:
16 divided by 87 is 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 87

Going ahead to step 3:
161 divided by 87 is 1 with a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 87 from 161 to get 74.
Append the next digit (3) from the dividend to 74 and continue with: 743 / 87

Step 4:
87 goes into 743 8 times with a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 696 from 743 leaves us with 47.
Grab the next digit (1) from the dividend, add it to 47, then carry on: 471 / 87

Let's proceed to step 5:
The number 87 fits into 471 5 times, leaving a remainder of 36.
Write down 5 as next digit of the result. 
Result so far: 185.0
If we subtract 435 from 471, we get 36.
Bring next digit (4) of the dividend behind the 36 and repeat the process: 364 / 87

On to step 6:
87 goes into 364 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 1854.0
Deduct 348 from 364 and we're left with 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 87

Step 7:
When dividing 160 by 87, we get 1 with a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 18541.0
If we take 87 away from 160, we end up with 73.
Fetch the next digit (0) from the dividend, attach it to 73 and continue: 730 / 87

Advancing to step 8:
87 can be fit into 730 8 times, resulting in a remainder of 34.
The next digit of our result is 8. 
Result so far: 185418.0
If we subtract 696 from 730, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
The number 87 fits into 340 3 times, leaving a remainder of 79.
Use 3 as the next digit of our solution. 
Result so far: 185418.3
If we subtract 261 from 340, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 10:
If we divide 790 by 87, we get 9 and a remainder of 7.
The next digit of our result is 9. 
Result so far: 185418.39
The remainder is 7 after subtracting 783 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 11:
87 goes into 70 0 times with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 185418.39
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 12:
700 divided by 87 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 185418.3908
If we subtract 696 from 700, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
If we divide 40 by 87, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 185418.3908
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
400 divided by 87 is 4 with a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 185418.390804
Subtracting 348 from 400 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 15:
87 can be fit into 520 5 times, resulting in a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 185418.3908045
Subtract 435 from 520 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 16:
If we divide 850 by 87, we get 9 and a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 185418.39080459
Subtract 783 from 850 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The quotient of the division is 185418.39080459, and the remainder is 6.7e-08.
