84487671 ÷ 439 
We want to figure out the number of times 84487671 can be divided by 439.

Step 1:
439 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 439

On to step 2:
439 goes into 84 0 times with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Append the next digit (4) from the dividend to 84 and continue with: 844 / 439

Going ahead to step 3:
844 divided by 439 is 1 with a remainder of 405.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 439 from 844, we get 405.
Fetch the next digit (8) from the dividend, attach it to 405 and continue: 4058 / 439

Advancing to step 4:
The number 439 fits into 4058 9 times, leaving a remainder of 107.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 3951 from 4058 and we're left with 107.
Grab the next digit (7) from the dividend, add it to 107, then carry on: 1077 / 439

Moving on to step 5:
When dividing 1077 by 439, we get 2 with a remainder of 199.
Write down 2 as next digit of the result. 
Result so far: 192.0
The remainder is 199 after subtracting 878 from 1077.
Bring next digit (6) of the dividend behind the 199 and repeat the process: 1996 / 439

On to step 6:
If we divide 1996 by 439, we get 4 and a remainder of 240.
Record the quotient 4 as the next digit in the result. 
Result so far: 1924.0
Deduct 1756 from 1996 and we're left with 240.
Take the next digit (7) from the dividend and append it to 240, then repeat: 2407 / 439

Step 7:
2407 divided by 439 is 5 with a remainder of 212.
Put 5 as the next digit of the answer. 
Result so far: 19245.0
If we take 2195 away from 2407, we end up with 212.
Grab the next digit (1) from the dividend, add it to 212, then carry on: 2121 / 439

Let's proceed to step 8:
When dividing 2121 by 439, we get 4 with a remainder of 365.
The next digit of our result is 4. 
Result so far: 192454.0
If we subtract 1756 from 2121, we get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

On to step 9:
439 can be fit into 3650 8 times, resulting in a remainder of 138.
The number 8 becomes the next digit in our result. 
Result so far: 192454.8
Subtracting 3512 from 3650 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 10:
1380 divided by 439 is 3 with a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 192454.83
If we take 1317 away from 1380, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 11:
439 goes into 630 1 times with a remainder of 191.
Put 1 as the next digit of the answer. 
Result so far: 192454.831
Subtract 439 from 630 to get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Step 12:
The number 439 fits into 1910 4 times, leaving a remainder of 154.
The number 4 becomes the next digit in our result. 
Result so far: 192454.8314
Deduct 1756 from 1910 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Let's proceed to step 13:
If we divide 1540 by 439, we get 3 and a remainder of 223.
The number 3 becomes the next digit in our result. 
Result so far: 192454.83143
Subtracting 1317 from 1540 leaves us with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Going ahead to step 14:
439 can be fit into 2230 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 192454.831435
Deduct 2195 from 2230 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 15:
350 divided by 439 is 0 with a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 192454.831435
If we subtract 0 from 350, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 16:
The number 439 fits into 3500 7 times, leaving a remainder of 427.
Use 7 as the next digit of our solution. 
Result so far: 192454.83143507
Deduct 3073 from 3500 and we're left with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

In conclusion, the division gives 192454.83143507 with a balance of 4.27e-07.
