Let's divide 87584840 by 671
The aim is to understand the frequency of 671 in 87584840.

On to step 1:
671 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 671

Going ahead to step 2:
If we divide 87 by 671, we get 0 and a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Include the next digit (5) from the dividend after 87, then repeat: 875 / 671

On to step 3:
The number 671 fits into 875 1 times, leaving a remainder of 204.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 671 from 875, we get 204.
Append the next digit (8) from the dividend to 204 and continue with: 2048 / 671

On to step 4:
If we divide 2048 by 671, we get 3 and a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 2013 from 2048 to get 35.
Include the next digit (4) from the dividend after 35, then repeat: 354 / 671

Moving on to step 5:
671 goes into 354 0 times with a remainder of 354.
Write down 0 as next digit of the result. 
Result so far: 130.0
The remainder is 354 after subtracting 0 from 354.
Include the next digit (8) from the dividend after 354, then repeat: 3548 / 671

Moving on to step 6:
3548 divided by 671 is 5 with a remainder of 193.
The next digit of our result is 5. 
Result so far: 1305.0
Deduct 3355 from 3548 and we're left with 193.
Grab the next digit (4) from the dividend, add it to 193, then carry on: 1934 / 671

On to step 7:
1934 divided by 671 is 2 with a remainder of 592.
The number 2 becomes the next digit in our result. 
Result so far: 13052.0
If we take 1342 away from 1934, we end up with 592.
Take the next digit (0) from the dividend and append it to 592, then repeat: 5920 / 671

On to step 8:
5920 divided by 671 is 8 with a remainder of 552.
Write down 8 as next digit of the result. 
Result so far: 130528.0
Deduct 5368 from 5920 and we're left with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 9:
The number 671 fits into 5520 8 times, leaving a remainder of 152.
Put 8 as the next digit of the answer. 
Result so far: 130528.8
Subtract 5368 from 5520 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 10:
671 goes into 1520 2 times with a remainder of 178.
Record the quotient 2 as the next digit in the result. 
Result so far: 130528.82
Subtracting 1342 from 1520 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 11:
When dividing 1780 by 671, we get 2 with a remainder of 438.
The number 2 becomes the next digit in our result. 
Result so far: 130528.822
Subtract 1342 from 1780 to get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Our division results in 130528.822 with a remaining 0.0438.
