354100 ÷ 70 
The aim is to understand the frequency of 70 in 354100.

Step 1:
70 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 70

Step 2:
70 goes into 35 0 times with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Bring next digit (4) of the dividend behind the 35 and repeat the process: 354 / 70

Moving on to step 3:
When dividing 354 by 70, we get 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 350 from 354, we get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 70

Going ahead to step 4:
If we divide 41 by 70, we get 0 and a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtract 0 from 41 to get 41.
Fetch the next digit (0) from the dividend, attach it to 41 and continue: 410 / 70

Advancing to step 5:
The number 70 fits into 410 5 times, leaving a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 505.0
Subtract 350 from 410 to get 60.
Fetch the next digit (0) from the dividend, attach it to 60 and continue: 600 / 70

Advancing to step 6:
When dividing 600 by 70, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 5058.0
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.

Step 7:
400 divided by 70 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 5058.5
If we take 350 away from 400, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
500 divided by 70 is 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 5058.57
Subtracting 490 from 500 leaves us 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.

On to step 9:
When dividing 100 by 70, we get 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 5058.571
If we take 70 away from 100, we end up 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.

Step 10:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 5058.5714
Subtracting 280 from 300 leaves us 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.

Advancing to step 11:
200 divided by 70 is 2 with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 5058.57142
If we subtract 140 from 200, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
The number 70 fits into 600 8 times, leaving a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 5058.571428
If we take 560 away from 600, we end up 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.

On to step 13:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 5058.5714285
Subtract 350 from 400 to 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.

Advancing to step 14:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 5058.57142857
Subtract 490 from 500 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 5058.57142857 and a remainder of 1e-08.
