70971604 divided by 187 
The aim is to understand the frequency of 187 in 70971604.

Let's proceed to step 1:
If we divide 7 by 187, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 187

On to step 2:
187 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Append the next digit (9) from the dividend to 70 and continue with: 709 / 187

Advancing to step 3:
187 goes into 709 3 times with a remainder of 148.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 561 away from 709, we end up with 148.
Include the next digit (7) from the dividend after 148, then repeat: 1487 / 187

Let's proceed to step 4:
187 goes into 1487 7 times with a remainder of 178.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Subtract 1309 from 1487 to get 178.
Append the next digit (1) from the dividend to 178 and continue with: 1781 / 187

Going ahead to step 5:
The number 187 fits into 1781 9 times, leaving a remainder of 98.
Record the quotient 9 as the next digit in the result. 
Result so far: 379.0
Subtracting 1683 from 1781 leaves us with 98.
Take the next digit (6) from the dividend and append it to 98, then repeat: 986 / 187

Moving on to step 6:
986 divided by 187 is 5 with a remainder of 51.
Record the quotient 5 as the next digit in the result. 
Result so far: 3795.0
If we take 935 away from 986, we end up with 51.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 187

Moving on to step 7:
If we divide 510 by 187, we get 2 and a remainder of 136.
The next digit of our result is 2. 
Result so far: 37952.0
Subtracting 374 from 510 leaves us with 136.
Include the next digit (4) from the dividend after 136, then repeat: 1364 / 187

Moving on to step 8:
The number 187 fits into 1364 7 times, leaving a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 379527.0
The remainder is 55 after subtracting 1309 from 1364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 9:
187 goes into 550 2 times with a remainder of 176.
Use 2 as the next digit of our solution. 
Result so far: 379527.2
Subtract 374 from 550 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 10:
If we divide 1760 by 187, we get 9 and a remainder of 77.
Write down 9 as next digit of the result. 
Result so far: 379527.29
If we subtract 1683 from 1760, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 11:
When dividing 770 by 187, we get 4 with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 379527.294
Subtract 748 from 770 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
220 divided by 187 is 1 with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 379527.2941
Subtracting 187 from 220 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 13:
If we divide 330 by 187, we get 1 and a remainder of 143.
The number 1 becomes the next digit in our result. 
Result so far: 379527.29411
Subtracting 187 from 330 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

The quotient of the division is 379527.29411, and the remainder is 0.000143.
