76457143 ÷ 125 
The aim is to understand the frequency of 125 in 76457143.

Let's proceed to step 1:
125 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 125

Advancing to step 2:
If we divide 76 by 125, we get 0 and a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Bring next digit (4) of the dividend behind the 76 and repeat the process: 764 / 125

On to step 3:
125 can be fit into 764 6 times, resulting in a remainder of 14.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 750 from 764, we get 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 125

Advancing to step 4:
125 goes into 145 1 times with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 61.0
Deduct 125 from 145 and we're left with 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 125

Going ahead to step 5:
If we divide 207 by 125, we get 1 and a remainder of 82.
The next digit of our result is 1. 
Result so far: 611.0
If we subtract 125 from 207, we get 82.
Include the next digit (1) from the dividend after 82, then repeat: 821 / 125

Advancing to step 6:
When dividing 821 by 125, we get 6 with a remainder of 71.
Use 6 as the next digit of our solution. 
Result so far: 6116.0
If we subtract 750 from 821, we get 71.
Bring next digit (4) of the dividend behind the 71 and repeat the process: 714 / 125

Going ahead to step 7:
If we divide 714 by 125, we get 5 and a remainder of 89.
Put 5 as the next digit of the answer. 
Result so far: 61165.0
Subtract 625 from 714 to get 89.
Grab the next digit (3) from the dividend, add it to 89, then carry on: 893 / 125

On to step 8:
893 divided by 125 is 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 611657.0
Subtracting 875 from 893 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
125 can be fit into 180 1 times, resulting in a remainder of 55.
Put 1 as the next digit of the answer. 
Result so far: 611657.1
Deduct 125 from 180 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 10:
125 goes into 550 4 times with a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 611657.14
Subtracting 500 from 550 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
When dividing 500 by 125, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 611657.144
If we subtract 500 from 500, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 611657.144 with a remaining 0.0.
