We divide 431980 by 84
We want to divide 431980 by 84.

Let's proceed to step 1:
If we divide 4 by 84, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 84

Advancing to step 2:
When dividing 43 by 84, we get 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 84

Step 3:
The number 84 fits into 431 5 times, leaving a remainder of 11.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 420 from 431 and we're left with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 84

Going ahead to step 4:
119 divided by 84 is 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtracting 84 from 119 leaves us with 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 84

Let's proceed to step 5:
358 divided by 84 is 4 with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 514.0
If we take 336 away from 358, we end up with 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 84

On to step 6:
If we divide 220 by 84, we get 2 and a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 5142.0
If we take 168 away from 220, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 7:
84 can be fit into 520 6 times, resulting in a remainder of 16.
The next digit of our result is 6. 
Result so far: 5142.6
If we subtract 504 from 520, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
When dividing 160 by 84, we get 1 with a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 5142.61
Deduct 84 from 160 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 9:
If we divide 760 by 84, we get 9 and a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 5142.619
The remainder is 4 after subtracting 756 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
The number 84 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 5142.619
Deduct 0 from 40 and we're left 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.

Advancing to step 11:
If we divide 400 by 84, we get 4 and a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 5142.61904
Subtract 336 from 400 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
640 divided by 84 is 7 with a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 5142.619047
Deduct 588 from 640 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 13:
If we divide 520 by 84, we get 6 and a remainder of 16.
The next digit of our result is 6. 
Result so far: 5142.6190476
If we subtract 504 from 520, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
84 goes into 160 1 times with a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 5142.61904761
If we take 84 away from 160, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 5142.61904761 with a remaining 7.6e-08.
