We divide 70435141 by 648
The aim is to understand the frequency of 648 in 70435141.

Step 1:
648 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 648

Advancing to step 2:
648 goes into 70 0 times with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Include the next digit (4) from the dividend after 70, then repeat: 704 / 648

Let's proceed to step 3:
If we divide 704 by 648, we get 1 and a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 648 from 704, we get 56.
Include the next digit (3) from the dividend after 56, then repeat: 563 / 648

Advancing to step 4:
When dividing 563 by 648, we get 0 with a remainder of 563.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 563 after subtracting 0 from 563.
Include the next digit (5) from the dividend after 563, then repeat: 5635 / 648

Moving on to step 5:
The number 648 fits into 5635 8 times, leaving a remainder of 451.
The next digit of our result is 8. 
Result so far: 108.0
If we take 5184 away from 5635, we end up with 451.
Grab the next digit (1) from the dividend, add it to 451, then carry on: 4511 / 648

Going ahead to step 6:
If we divide 4511 by 648, we get 6 and a remainder of 623.
The number 6 becomes the next digit in our result. 
Result so far: 1086.0
The remainder is 623 after subtracting 3888 from 4511.
Append the next digit (4) from the dividend to 623 and continue with: 6234 / 648

On to step 7:
6234 divided by 648 is 9 with a remainder of 402.
Record the quotient 9 as the next digit in the result. 
Result so far: 10869.0
The remainder is 402 after subtracting 5832 from 6234.
Fetch the next digit (1) from the dividend, attach it to 402 and continue: 4021 / 648

Let's proceed to step 8:
When dividing 4021 by 648, we get 6 with a remainder of 133.
The next digit of our result is 6. 
Result so far: 108696.0
The remainder is 133 after subtracting 3888 from 4021.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Let's proceed to step 9:
648 goes into 1330 2 times with a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 108696.2
Subtract 1296 from 1330 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
340 divided by 648 is 0 with a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 108696.2
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 11:
The number 648 fits into 3400 5 times, leaving a remainder of 160.
Record the quotient 5 as the next digit in the result. 
Result so far: 108696.205
Deduct 3240 from 3400 and we're left 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.

Step 12:
1600 divided by 648 is 2 with a remainder of 304.
Write down 2 as next digit of the result. 
Result so far: 108696.2052
Deduct 1296 from 1600 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 13:
The number 648 fits into 3040 4 times, leaving a remainder of 448.
The next digit of our result is 4. 
Result so far: 108696.20524
The remainder is 448 after subtracting 2592 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Let's proceed to step 14:
648 can be fit into 4480 6 times, resulting in a remainder of 592.
The next digit of our result is 6. 
Result so far: 108696.205246
If we subtract 3888 from 4480, we get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Going ahead to step 15:
648 goes into 5920 9 times with a remainder of 88.
The number 9 becomes the next digit in our result. 
Result so far: 108696.2052469
The remainder is 88 after subtracting 5832 from 5920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 16:
The number 648 fits into 880 1 times, leaving a remainder of 232.
Put 1 as the next digit of the answer. 
Result so far: 108696.20524691
Deduct 648 from 880 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

The quotient of the division is 108696.20524691, and the remainder is 2.32e-07.
