84264971 ÷ 391 
We're looking to find how many times 391 goes into 84264971.

On to step 1:
The number 391 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 391

Moving on to step 2:
84 divided by 391 is 0 with a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Grab the next digit (2) from the dividend, add it to 84, then carry on: 842 / 391

Moving on to step 3:
391 can be fit into 842 2 times, resulting in a remainder of 60.
The next digit of our result is 2. 
Result so far: 2.0
If we take 782 away from 842, we end up with 60.
Take the next digit (6) from the dividend and append it to 60, then repeat: 606 / 391

Going ahead to step 4:
When dividing 606 by 391, we get 1 with a remainder of 215.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 391 away from 606, we end up with 215.
Append the next digit (4) from the dividend to 215 and continue with: 2154 / 391

Going ahead to step 5:
The number 391 fits into 2154 5 times, leaving a remainder of 199.
Write down 5 as next digit of the result. 
Result so far: 215.0
The remainder is 199 after subtracting 1955 from 2154.
Bring next digit (9) of the dividend behind the 199 and repeat the process: 1999 / 391

Going ahead to step 6:
If we divide 1999 by 391, we get 5 and a remainder of 44.
The next digit of our result is 5. 
Result so far: 2155.0
If we subtract 1955 from 1999, we get 44.
Fetch the next digit (7) from the dividend, attach it to 44 and continue: 447 / 391

Step 7:
When dividing 447 by 391, we get 1 with a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 21551.0
Deduct 391 from 447 and we're left with 56.
Grab the next digit (1) from the dividend, add it to 56, then carry on: 561 / 391

Going ahead to step 8:
The number 391 fits into 561 1 times, leaving a remainder of 170.
Put 1 as the next digit of the answer. 
Result so far: 215511.0
If we subtract 391 from 561, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 9:
The number 391 fits into 1700 4 times, leaving a remainder of 136.
The number 4 becomes the next digit in our result. 
Result so far: 215511.4
Deduct 1564 from 1700 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 10:
When dividing 1360 by 391, we get 3 with a remainder of 187.
Write down 3 as next digit of the result. 
Result so far: 215511.43
If we take 1173 away from 1360, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Going ahead to step 11:
If we divide 1870 by 391, we get 4 and a remainder of 306.
Write down 4 as next digit of the result. 
Result so far: 215511.434
Deduct 1564 from 1870 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Let's proceed to step 12:
When dividing 3060 by 391, we get 7 with a remainder of 323.
The next digit of our result is 7. 
Result so far: 215511.4347
Deduct 2737 from 3060 and we're left with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Let's proceed to step 13:
391 can be fit into 3230 8 times, resulting in a remainder of 102.
Use 8 as the next digit of our solution. 
Result so far: 215511.43478
The remainder is 102 after subtracting 3128 from 3230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 14:
When dividing 1020 by 391, we get 2 with a remainder of 238.
The number 2 becomes the next digit in our result. 
Result so far: 215511.434782
If we take 782 away from 1020, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 15:
2380 divided by 391 is 6 with a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 215511.4347826
Subtract 2346 from 2380 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 16:
340 divided by 391 is 0 with a remainder of 340.
The next digit of our result is 0. 
Result so far: 215511.4347826
If we take 0 away from 340, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

In conclusion, the division gives 215511.4347826 with a balance of 3.4e-07.
