85100378 divided by 687 
The aim is to understand the frequency of 687 in 85100378.

Moving on to step 1:
687 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 687

Moving on to step 2:
If we divide 85 by 687, we get 0 and a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Append the next digit (1) from the dividend to 85 and continue with: 851 / 687

Going ahead to step 3:
When dividing 851 by 687, we get 1 with a remainder of 164.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 687 from 851 leaves us with 164.
Fetch the next digit (0) from the dividend, attach it to 164 and continue: 1640 / 687

Advancing to step 4:
When dividing 1640 by 687, we get 2 with a remainder of 266.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 1374 from 1640 leaves us with 266.
Bring next digit (0) of the dividend behind the 266 and repeat the process: 2660 / 687

Moving on to step 5:
If we divide 2660 by 687, we get 3 and a remainder of 599.
Put 3 as the next digit of the answer. 
Result so far: 123.0
If we subtract 2061 from 2660, we get 599.
Append the next digit (3) from the dividend to 599 and continue with: 5993 / 687

Step 6:
687 goes into 5993 8 times with a remainder of 497.
Use 8 as the next digit of our solution. 
Result so far: 1238.0
If we subtract 5496 from 5993, we get 497.
Include the next digit (7) from the dividend after 497, then repeat: 4977 / 687

On to step 7:
When dividing 4977 by 687, we get 7 with a remainder of 168.
Use 7 as the next digit of our solution. 
Result so far: 12387.0
If we subtract 4809 from 4977, we get 168.
Take the next digit (8) from the dividend and append it to 168, then repeat: 1688 / 687

Advancing to step 8:
1688 divided by 687 is 2 with a remainder of 314.
The number 2 becomes the next digit in our result. 
Result so far: 123872.0
If we take 1374 away from 1688, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 9:
When dividing 3140 by 687, we get 4 with a remainder of 392.
The number 4 becomes the next digit in our result. 
Result so far: 123872.4
Subtract 2748 from 3140 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 10:
When dividing 3920 by 687, we get 5 with a remainder of 485.
Write down 5 as next digit of the result. 
Result so far: 123872.45
If we take 3435 away from 3920, we end up with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 11:
When dividing 4850 by 687, we get 7 with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 123872.457
Subtracting 4809 from 4850 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 12:
When dividing 410 by 687, we get 0 with a remainder of 410.
Use 0 as the next digit of our solution. 
Result so far: 123872.457
The remainder is 410 after subtracting 0 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 13:
If we divide 4100 by 687, we get 5 and a remainder of 665.
The next digit of our result is 5. 
Result so far: 123872.45705
Subtract 3435 from 4100 to get 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Step 14:
687 can be fit into 6650 9 times, resulting in a remainder of 467.
Record the quotient 9 as the next digit in the result. 
Result so far: 123872.457059
If we take 6183 away from 6650, we end up with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Advancing to step 15:
When dividing 4670 by 687, we get 6 with a remainder of 548.
The number 6 becomes the next digit in our result. 
Result so far: 123872.4570596
If we take 4122 away from 4670, we end up with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Going ahead to step 16:
If we divide 5480 by 687, we get 7 and a remainder of 671.
Record the quotient 7 as the next digit in the result. 
Result so far: 123872.45705967
Subtract 4809 from 5480 to get 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

The final result is 123872.45705967 with a remainder of 6.71e-07.
