We're dividing 35513648 by 70 
The aim is to understand the frequency of 70 in 35513648.

Moving on to step 1:
3 divided by 70 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 70

Step 2:
The number 70 fits into 35 0 times, leaving a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 70

On to step 3:
70 can be fit into 355 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 350 from 355, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 70

Let's proceed to step 4:
70 can be fit into 51 0 times, resulting in a remainder of 51.
The next digit of our result is 0. 
Result so far: 50.0
Deduct 0 from 51 and we're left with 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 70

Going ahead to step 5:
When dividing 513 by 70, we get 7 with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 507.0
If we take 490 away from 513, we end up with 23.
Fetch the next digit (6) from the dividend, attach it to 23 and continue: 236 / 70

Step 6:
The number 70 fits into 236 3 times, leaving a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 5073.0
Deduct 210 from 236 and we're left with 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 70

On to step 7:
70 can be fit into 264 3 times, resulting in a remainder of 54.
The next digit of our result is 3. 
Result so far: 50733.0
Deduct 210 from 264 and we're left with 54.
Take the next digit (8) from the dividend and append it to 54, then repeat: 548 / 70

Step 8:
548 divided by 70 is 7 with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 507337.0
The remainder is 58 after subtracting 490 from 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 9:
If we divide 580 by 70, we get 8 and a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 507337.8
Deduct 560 from 580 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
200 divided by 70 is 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 507337.82
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
600 divided by 70 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 507337.828
Deduct 560 from 600 and we're left 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.

Moving on to step 12:
If we divide 400 by 70, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 507337.8285
If we subtract 350 from 400, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
70 goes into 500 7 times with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 507337.82857
Deduct 490 from 500 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
The number 70 fits into 100 1 times, leaving a remainder of 30.
The next digit of our result is 1. 
Result so far: 507337.828571
Deduct 70 from 100 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 15:
If we divide 300 by 70, we get 4 and a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 507337.8285714
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 16:
70 can be fit into 200 2 times, resulting in a remainder of 60.
The next digit of our result is 2. 
Result so far: 507337.82857142
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 507337.82857142 with a remainder of 6e-08.
