We look at the division of 31395984 by 430 
We want to divide 31395984 by 430.

Going ahead to step 1:
The number 430 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 430

Advancing to step 2:
430 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 430

On to step 3:
430 goes into 313 0 times with a remainder of 313.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 313 to get 313.
Grab the next digit (9) from the dividend, add it to 313, then carry on: 3139 / 430

Going ahead to step 4:
When dividing 3139 by 430, we get 7 with a remainder of 129.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 3010 from 3139, we get 129.
Fetch the next digit (5) from the dividend, attach it to 129 and continue: 1295 / 430

Moving on to step 5:
When dividing 1295 by 430, we get 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 73.0
The remainder is 5 after subtracting 1290 from 1295.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 430

Moving on to step 6:
430 can be fit into 59 0 times, resulting in a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 730.0
Deduct 0 from 59 and we're left with 59.
Append the next digit (8) from the dividend to 59 and continue with: 598 / 430

Advancing to step 7:
When dividing 598 by 430, we get 1 with a remainder of 168.
Record the quotient 1 as the next digit in the result. 
Result so far: 7301.0
If we take 430 away from 598, we end up with 168.
Fetch the next digit (4) from the dividend, attach it to 168 and continue: 1684 / 430

Going ahead to step 8:
When dividing 1684 by 430, we get 3 with a remainder of 394.
The number 3 becomes the next digit in our result. 
Result so far: 73013.0
If we take 1290 away from 1684, we end up with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 9:
3940 divided by 430 is 9 with a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 73013.9
Deduct 3870 from 3940 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
When dividing 700 by 430, we get 1 with a remainder of 270.
Put 1 as the next digit of the answer. 
Result so far: 73013.91
If we take 430 away from 700, we end up 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 11:
2700 divided by 430 is 6 with a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 73013.916
If we subtract 2580 from 2700, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 12:
The number 430 fits into 1200 2 times, leaving a remainder of 340.
Write down 2 as next digit of the result. 
Result so far: 73013.9162
Subtract 860 from 1200 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 13:
The number 430 fits into 3400 7 times, leaving a remainder of 390.
The next digit of our result is 7. 
Result so far: 73013.91627
Subtract 3010 from 3400 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 14:
When dividing 3900 by 430, we get 9 with a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 73013.916279
The remainder is 30 after subtracting 3870 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 15:
When dividing 300 by 430, we get 0 with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 73013.916279
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 16:
3000 divided by 430 is 6 with a remainder of 420.
Use 6 as the next digit of our solution. 
Result so far: 73013.91627906
The remainder is 420 after subtracting 2580 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

After the division, we end up with 73013.91627906 and a remainder of 4.2e-07.
