70676370 ÷ 431 
We want to divide 70676370 by 431.

Step 1:
7 divided by 431 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 431

On to step 2:
The number 431 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Include the next digit (6) from the dividend after 70, then repeat: 706 / 431

Step 3:
431 goes into 706 1 times with a remainder of 275.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 431 from 706 and we're left with 275.
Bring next digit (7) of the dividend behind the 275 and repeat the process: 2757 / 431

Advancing to step 4:
If we divide 2757 by 431, we get 6 and a remainder of 171.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 2586 away from 2757, we end up with 171.
Grab the next digit (6) from the dividend, add it to 171, then carry on: 1716 / 431

Going ahead to step 5:
431 goes into 1716 3 times with a remainder of 423.
The number 3 becomes the next digit in our result. 
Result so far: 163.0
Subtract 1293 from 1716 to get 423.
Grab the next digit (3) from the dividend, add it to 423, then carry on: 4233 / 431

On to step 6:
4233 divided by 431 is 9 with a remainder of 354.
The next digit of our result is 9. 
Result so far: 1639.0
The remainder is 354 after subtracting 3879 from 4233.
Grab the next digit (7) from the dividend, add it to 354, then carry on: 3547 / 431

Let's proceed to step 7:
431 goes into 3547 8 times with a remainder of 99.
The next digit of our result is 8. 
Result so far: 16398.0
The remainder is 99 after subtracting 3448 from 3547.
Include the next digit (0) from the dividend after 99, then repeat: 990 / 431

Going ahead to step 8:
The number 431 fits into 990 2 times, leaving a remainder of 128.
Record the quotient 2 as the next digit in the result. 
Result so far: 163982.0
Subtract 862 from 990 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 9:
431 goes into 1280 2 times with a remainder of 418.
Use 2 as the next digit of our solution. 
Result so far: 163982.2
Subtracting 862 from 1280 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Advancing to step 10:
If we divide 4180 by 431, we get 9 and a remainder of 301.
Put 9 as the next digit of the answer. 
Result so far: 163982.29
Subtract 3879 from 4180 to get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Step 11:
431 goes into 3010 6 times with a remainder of 424.
Put 6 as the next digit of the answer. 
Result so far: 163982.296
Subtracting 2586 from 3010 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Step 12:
If we divide 4240 by 431, we get 9 and a remainder of 361.
The number 9 becomes the next digit in our result. 
Result so far: 163982.2969
The remainder is 361 after subtracting 3879 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

On to step 13:
431 goes into 3610 8 times with a remainder of 162.
Write down 8 as next digit of the result. 
Result so far: 163982.29698
The remainder is 162 after subtracting 3448 from 3610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 14:
431 can be fit into 1620 3 times, resulting in a remainder of 327.
Record the quotient 3 as the next digit in the result. 
Result so far: 163982.296983
Subtracting 1293 from 1620 leaves us with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Going ahead to step 15:
The number 431 fits into 3270 7 times, leaving a remainder of 253.
The next digit of our result is 7. 
Result so far: 163982.2969837
Deduct 3017 from 3270 and we're left with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Moving on to step 16:
431 goes into 2530 5 times with a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 163982.29698375
The remainder is 375 after subtracting 2155 from 2530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

In conclusion, the division gives 163982.29698375 with a balance of 3.75e-07.
