353543 divided by 70 
We want to figure out the number of times 353543 can be divided by 70.

Step 1:
When dividing 3 by 70, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 70

Advancing to step 2:
If we divide 35 by 70, we get 0 and a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 70

Step 3:
The number 70 fits into 353 5 times, leaving a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 350 from 353 and we're left with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 70

Moving on to step 4:
70 goes into 35 0 times with a remainder of 35.
The next digit of our result is 0. 
Result so far: 50.0
Deduct 0 from 35 and we're left with 35.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 70

Going ahead to step 5:
If we divide 354 by 70, we get 5 and a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 505.0
If we subtract 350 from 354, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 70

Moving on to step 6:
If we divide 43 by 70, we get 0 and a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 5050.0
Deduct 0 from 43 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
The number 70 fits into 430 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 5050.6
Subtract 420 from 430 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.

Step 8:
100 divided by 70 is 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 5050.61
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 9:
If we divide 300 by 70, we get 4 and a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 5050.614
If we take 280 away from 300, we end up 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.

Let's proceed to step 10:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 5050.6142
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:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 5050.61428
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 12:
When dividing 400 by 70, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 5050.614285
The remainder is 50 after subtracting 350 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
The number 70 fits into 500 7 times, leaving a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 5050.6142857
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 14:
When dividing 100 by 70, we get 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 5050.61428571
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.

Our division results in 5050.61428571 with a remaining 3e-08.
