43491811 divided by 70 
Our goal is to divide 43491811 by 70.

Going ahead to step 1:
When dividing 4 by 70, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 70

On to step 2:
70 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 70

Advancing to step 3:
The number 70 fits into 434 6 times, leaving a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 420 from 434 leaves us with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 70

Step 4:
70 can be fit into 149 2 times, resulting in a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 62.0
Deduct 140 from 149 and we're left with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 70

Advancing to step 5:
The number 70 fits into 91 1 times, leaving a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 621.0
Deduct 70 from 91 and we're left with 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 70

On to step 6:
218 divided by 70 is 3 with a remainder of 8.
The next digit of our result is 3. 
Result so far: 6213.0
Subtracting 210 from 218 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 70

Advancing to step 7:
If we divide 81 by 70, we get 1 and a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 62131.0
If we subtract 70 from 81, we get 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 70

On to step 8:
When dividing 111 by 70, we get 1 with a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 621311.0
If we take 70 away from 111, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 9:
410 divided by 70 is 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 621311.5
The remainder is 60 after subtracting 350 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
The number 70 fits into 600 8 times, leaving a remainder of 40.
The next digit of our result is 8. 
Result so far: 621311.58
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.

Step 11:
When dividing 400 by 70, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 621311.585
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.

Let's proceed to step 12:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 621311.5857
If we subtract 490 from 500, we 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.

Advancing to step 13:
When dividing 100 by 70, we get 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 621311.58571
Subtracting 70 from 100 leaves us 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 14:
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: 621311.585714
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 15:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 621311.5857142
Subtract 140 from 200 to 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.

Advancing to step 16:
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: 621311.58571428
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.

The final result is 621311.58571428 with a remainder of 4e-08.
