We look at the division of 47400623 by 870 
The aim is to understand the frequency of 870 in 47400623.

On to step 1:
The number 870 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 870

Going ahead to step 2:
When dividing 47 by 870, we get 0 with a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 47 and we're left with 47.
Fetch the next digit (4) from the dividend, attach it to 47 and continue: 474 / 870

On to step 3:
870 can be fit into 474 0 times, resulting in a remainder of 474.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 474 leaves us with 474.
Take the next digit (0) from the dividend and append it to 474, then repeat: 4740 / 870

Moving on to step 4:
870 goes into 4740 5 times with a remainder of 390.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 4350 from 4740, we get 390.
Take the next digit (0) from the dividend and append it to 390, then repeat: 3900 / 870

Going ahead to step 5:
If we divide 3900 by 870, we get 4 and a remainder of 420.
Put 4 as the next digit of the answer. 
Result so far: 54.0
If we take 3480 away from 3900, we end up with 420.
Bring next digit (6) of the dividend behind the 420 and repeat the process: 4206 / 870

Step 6:
870 can be fit into 4206 4 times, resulting in a remainder of 726.
Record the quotient 4 as the next digit in the result. 
Result so far: 544.0
If we subtract 3480 from 4206, we get 726.
Take the next digit (2) from the dividend and append it to 726, then repeat: 7262 / 870

Going ahead to step 7:
870 goes into 7262 8 times with a remainder of 302.
The next digit of our result is 8. 
Result so far: 5448.0
Subtracting 6960 from 7262 leaves us with 302.
Append the next digit (3) from the dividend to 302 and continue with: 3023 / 870

Advancing to step 8:
If we divide 3023 by 870, we get 3 and a remainder of 413.
Record the quotient 3 as the next digit in the result. 
Result so far: 54483.0
If we take 2610 away from 3023, we end up with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Step 9:
4130 divided by 870 is 4 with a remainder of 650.
The next digit of our result is 4. 
Result so far: 54483.4
Subtracting 3480 from 4130 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Let's proceed to step 10:
If we divide 6500 by 870, we get 7 and a remainder of 410.
Put 7 as the next digit of the answer. 
Result so far: 54483.47
The remainder is 410 after subtracting 6090 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 11:
870 can be fit into 4100 4 times, resulting in a remainder of 620.
Write down 4 as next digit of the result. 
Result so far: 54483.474
Subtracting 3480 from 4100 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 12:
The number 870 fits into 6200 7 times, leaving a remainder of 110.
Record the quotient 7 as the next digit in the result. 
Result so far: 54483.4747
Deduct 6090 from 6200 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 13:
If we divide 1100 by 870, we get 1 and a remainder of 230.
Put 1 as the next digit of the answer. 
Result so far: 54483.47471
If we subtract 870 from 1100, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 14:
The number 870 fits into 2300 2 times, leaving a remainder of 560.
The next digit of our result is 2. 
Result so far: 54483.474712
The remainder is 560 after subtracting 1740 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 15:
If we divide 5600 by 870, we get 6 and a remainder of 380.
Record the quotient 6 as the next digit in the result. 
Result so far: 54483.4747126
If we take 5220 away from 5600, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 16:
3800 divided by 870 is 4 with a remainder of 320.
Write down 4 as next digit of the result. 
Result so far: 54483.47471264
Subtracting 3480 from 3800 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Our division results in 54483.47471264 with a remaining 3.2e-07.
