70668716 ÷ 431 
We want to divide 70668716 by 431.

On to step 1:
The number 431 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 431

On to step 2:
70 divided by 431 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Fetch the next digit (6) from the dividend, attach it to 70 and continue: 706 / 431

Going ahead to step 3:
When dividing 706 by 431, we get 1 with a remainder of 275.
The next digit of our result is 1. 
Result so far: 1.0
If we take 431 away from 706, we end up with 275.
Include the next digit (6) from the dividend after 275, then repeat: 2756 / 431

Going ahead to step 4:
431 goes into 2756 6 times with a remainder of 170.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 2586 from 2756 leaves us with 170.
Grab the next digit (8) from the dividend, add it to 170, then carry on: 1708 / 431

Step 5:
431 goes into 1708 3 times with a remainder of 415.
Use 3 as the next digit of our solution. 
Result so far: 163.0
The remainder is 415 after subtracting 1293 from 1708.
Bring next digit (7) of the dividend behind the 415 and repeat the process: 4157 / 431

Moving on to step 6:
4157 divided by 431 is 9 with a remainder of 278.
Use 9 as the next digit of our solution. 
Result so far: 1639.0
Deduct 3879 from 4157 and we're left with 278.
Take the next digit (1) from the dividend and append it to 278, then repeat: 2781 / 431

Let's proceed to step 7:
When dividing 2781 by 431, we get 6 with a remainder of 195.
Put 6 as the next digit of the answer. 
Result so far: 16396.0
Subtracting 2586 from 2781 leaves us with 195.
Take the next digit (6) from the dividend and append it to 195, then repeat: 1956 / 431

Advancing to step 8:
If we divide 1956 by 431, we get 4 and a remainder of 232.
Write down 4 as next digit of the result. 
Result so far: 163964.0
Subtract 1724 from 1956 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 9:
The number 431 fits into 2320 5 times, leaving a remainder of 165.
The next digit of our result is 5. 
Result so far: 163964.5
If we take 2155 away from 2320, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 10:
If we divide 1650 by 431, we get 3 and a remainder of 357.
The number 3 becomes the next digit in our result. 
Result so far: 163964.53
Deduct 1293 from 1650 and we're left with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Advancing to step 11:
431 goes into 3570 8 times with a remainder of 122.
Write down 8 as next digit of the result. 
Result so far: 163964.538
The remainder is 122 after subtracting 3448 from 3570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 12:
When dividing 1220 by 431, we get 2 with a remainder of 358.
The next digit of our result is 2. 
Result so far: 163964.5382
Subtract 862 from 1220 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 13:
431 can be fit into 3580 8 times, resulting in a remainder of 132.
Record the quotient 8 as the next digit in the result. 
Result so far: 163964.53828
Subtracting 3448 from 3580 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 14:
The number 431 fits into 1320 3 times, leaving a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 163964.538283
Deduct 1293 from 1320 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 15:
If we divide 270 by 431, we get 0 and a remainder of 270.
Record the quotient 0 as the next digit in the result. 
Result so far: 163964.538283
Subtracting 0 from 270 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 16:
When dividing 2700 by 431, we get 6 with a remainder of 114.
The next digit of our result is 6. 
Result so far: 163964.53828306
If we subtract 2586 from 2700, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

After the division, we end up with 163964.53828306 and a remainder of 1.14e-07.
