83989664 ÷ 109 
Our goal is to divide 83989664 by 109.

On to step 1:
8 divided by 109 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 109

Step 2:
109 goes into 83 0 times with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Take the next digit (9) from the dividend and append it to 83, then repeat: 839 / 109

On to step 3:
When dividing 839 by 109, we get 7 with a remainder of 76.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 76 after subtracting 763 from 839.
Append the next digit (8) from the dividend to 76 and continue with: 768 / 109

Advancing to step 4:
109 can be fit into 768 7 times, resulting in a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Deduct 763 from 768 and we're left with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 109

Step 5:
When dividing 59 by 109, we get 0 with a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 770.0
If we take 0 away from 59, we end up with 59.
Grab the next digit (6) from the dividend, add it to 59, then carry on: 596 / 109

Let's proceed to step 6:
When dividing 596 by 109, we get 5 with a remainder of 51.
Record the quotient 5 as the next digit in the result. 
Result so far: 7705.0
Deduct 545 from 596 and we're left with 51.
Include the next digit (6) from the dividend after 51, then repeat: 516 / 109

On to step 7:
The number 109 fits into 516 4 times, leaving a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 77054.0
Deduct 436 from 516 and we're left with 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 109

Going ahead to step 8:
If we divide 804 by 109, we get 7 and a remainder of 41.
The next digit of our result is 7. 
Result so far: 770547.0
Subtract 763 from 804 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 9:
If we divide 410 by 109, we get 3 and a remainder of 83.
Write down 3 as next digit of the result. 
Result so far: 770547.3
Deduct 327 from 410 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 10:
When dividing 830 by 109, we get 7 with a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 770547.37
If we subtract 763 from 830, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 11:
109 can be fit into 670 6 times, resulting in a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 770547.376
If we take 654 away from 670, we end up with 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 12:
109 goes into 160 1 times with a remainder of 51.
The next digit of our result is 1. 
Result so far: 770547.3761
Subtract 109 from 160 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 13:
When dividing 510 by 109, we get 4 with a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 770547.37614
If we subtract 436 from 510, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 14:
740 divided by 109 is 6 with a remainder of 86.
The next digit of our result is 6. 
Result so far: 770547.376146
The remainder is 86 after subtracting 654 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 15:
When dividing 860 by 109, we get 7 with a remainder of 97.
Record the quotient 7 as the next digit in the result. 
Result so far: 770547.3761467
Deduct 763 from 860 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 16:
The number 109 fits into 970 8 times, leaving a remainder of 98.
Put 8 as the next digit of the answer. 
Result so far: 770547.37614678
Subtracting 872 from 970 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

The quotient of the division is 770547.37614678, and the remainder is 9.8e-08.
