70085878 ÷ 180 
The aim is to understand the frequency of 180 in 70085878.

Going ahead to step 1:
When dividing 7 by 180, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 180

Let's proceed to step 2:
When dividing 70 by 180, we get 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Take the next digit (0) from the dividend and append it to 70, then repeat: 700 / 180

Going ahead to step 3:
The number 180 fits into 700 3 times, leaving a remainder of 160.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 540 from 700 to get 160.
Fetch the next digit (8) from the dividend, attach it to 160 and continue: 1608 / 180

On to step 4:
180 can be fit into 1608 8 times, resulting in a remainder of 168.
Write down 8 as next digit of the result. 
Result so far: 38.0
The remainder is 168 after subtracting 1440 from 1608.
Fetch the next digit (5) from the dividend, attach it to 168 and continue: 1685 / 180

On to step 5:
180 can be fit into 1685 9 times, resulting in a remainder of 65.
Put 9 as the next digit of the answer. 
Result so far: 389.0
The remainder is 65 after subtracting 1620 from 1685.
Take the next digit (8) from the dividend and append it to 65, then repeat: 658 / 180

On to step 6:
The number 180 fits into 658 3 times, leaving a remainder of 118.
Record the quotient 3 as the next digit in the result. 
Result so far: 3893.0
If we take 540 away from 658, we end up with 118.
Fetch the next digit (7) from the dividend, attach it to 118 and continue: 1187 / 180

Advancing to step 7:
When dividing 1187 by 180, we get 6 with a remainder of 107.
Use 6 as the next digit of our solution. 
Result so far: 38936.0
If we take 1080 away from 1187, we end up with 107.
Append the next digit (8) from the dividend to 107 and continue with: 1078 / 180

On to step 8:
The number 180 fits into 1078 5 times, leaving a remainder of 178.
Put 5 as the next digit of the answer. 
Result so far: 389365.0
If we subtract 900 from 1078, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Let's proceed to step 9:
180 goes into 1780 9 times with a remainder of 160.
Record the quotient 9 as the next digit in the result. 
Result so far: 389365.9
Subtract 1620 from 1780 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 10:
When dividing 1600 by 180, we get 8 with a remainder of 160.
Record the quotient 8 as the next digit in the result. 
Result so far: 389365.98
Subtracting 1440 from 1600 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
180 can be fit into 1600 8 times, resulting in a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 389365.988
Subtracting 1440 from 1600 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The quotient of the division is 389365.988, and the remainder is 0.016.
