37878064 ÷ 870 
The aim is to understand the frequency of 870 in 37878064.

Step 1:
3 divided by 870 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 870

Step 2:
870 goes into 37 0 times with a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 870

Step 3:
The number 870 fits into 378 0 times, leaving a remainder of 378.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 378, we get 378.
Append the next digit (7) from the dividend to 378 and continue with: 3787 / 870

Let's proceed to step 4:
3787 divided by 870 is 4 with a remainder of 307.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 3480 from 3787 to get 307.
Fetch the next digit (8) from the dividend, attach it to 307 and continue: 3078 / 870

Step 5:
870 can be fit into 3078 3 times, resulting in a remainder of 468.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtracting 2610 from 3078 leaves us with 468.
Take the next digit (0) from the dividend and append it to 468, then repeat: 4680 / 870

Let's proceed to step 6:
870 can be fit into 4680 5 times, resulting in a remainder of 330.
Record the quotient 5 as the next digit in the result. 
Result so far: 435.0
Subtracting 4350 from 4680 leaves us with 330.
Append the next digit (6) from the dividend to 330 and continue with: 3306 / 870

Advancing to step 7:
870 can be fit into 3306 3 times, resulting in a remainder of 696.
The number 3 becomes the next digit in our result. 
Result so far: 4353.0
Subtracting 2610 from 3306 leaves us with 696.
Append the next digit (4) from the dividend to 696 and continue with: 6964 / 870

Let's proceed to step 8:
870 goes into 6964 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 43538.0
If we take 6960 away from 6964, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
If we divide 40 by 870, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 43538.0
Subtracting 0 from 40 leaves us with 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 10:
870 goes into 400 0 times with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 43538.0
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 43538.0 and a remainder of 0.4.
