83891711 ÷ 715 
We want to figure out the number of times 83891711 can be divided by 715.

Advancing to step 1:
The number 715 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 715

Advancing to step 2:
83 divided by 715 is 0 with a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Grab the next digit (8) from the dividend, add it to 83, then carry on: 838 / 715

Going ahead to step 3:
715 goes into 838 1 times with a remainder of 123.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 715 from 838 leaves us with 123.
Append the next digit (9) from the dividend to 123 and continue with: 1239 / 715

Going ahead to step 4:
715 can be fit into 1239 1 times, resulting in a remainder of 524.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 715 away from 1239, we end up with 524.
Fetch the next digit (1) from the dividend, attach it to 524 and continue: 5241 / 715

On to step 5:
715 can be fit into 5241 7 times, resulting in a remainder of 236.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
Subtract 5005 from 5241 to get 236.
Take the next digit (7) from the dividend and append it to 236, then repeat: 2367 / 715

Advancing to step 6:
When dividing 2367 by 715, we get 3 with a remainder of 222.
Use 3 as the next digit of our solution. 
Result so far: 1173.0
Subtract 2145 from 2367 to get 222.
Include the next digit (1) from the dividend after 222, then repeat: 2221 / 715

Moving on to step 7:
If we divide 2221 by 715, we get 3 and a remainder of 76.
Use 3 as the next digit of our solution. 
Result so far: 11733.0
If we take 2145 away from 2221, we end up with 76.
Bring next digit (1) of the dividend behind the 76 and repeat the process: 761 / 715

Moving on to step 8:
715 goes into 761 1 times with a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 117331.0
Deduct 715 from 761 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
460 divided by 715 is 0 with a remainder of 460.
The number 0 becomes the next digit in our result. 
Result so far: 117331.0
Deduct 0 from 460 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 10:
If we divide 4600 by 715, we get 6 and a remainder of 310.
The number 6 becomes the next digit in our result. 
Result so far: 117331.06
Deduct 4290 from 4600 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 11:
715 can be fit into 3100 4 times, resulting in a remainder of 240.
The number 4 becomes the next digit in our result. 
Result so far: 117331.064
If we take 2860 away from 3100, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 12:
2400 divided by 715 is 3 with a remainder of 255.
The number 3 becomes the next digit in our result. 
Result so far: 117331.0643
Subtract 2145 from 2400 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 13:
715 goes into 2550 3 times with a remainder of 405.
Put 3 as the next digit of the answer. 
Result so far: 117331.06433
The remainder is 405 after subtracting 2145 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

In conclusion, the division gives 117331.06433 with a balance of 0.000405.
