86669039 divided by 980 
Let's see how many times 980 fits into 86669039.

Going ahead to step 1:
980 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 980

Step 2:
980 can be fit into 86 0 times, resulting in a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Take the next digit (6) from the dividend and append it to 86, then repeat: 866 / 980

Going ahead to step 3:
980 goes into 866 0 times with a remainder of 866.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 866 and we're left with 866.
Take the next digit (6) from the dividend and append it to 866, then repeat: 8666 / 980

On to step 4:
980 goes into 8666 8 times with a remainder of 826.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 7840 from 8666 leaves us with 826.
Grab the next digit (9) from the dividend, add it to 826, then carry on: 8269 / 980

Moving on to step 5:
980 can be fit into 8269 8 times, resulting in a remainder of 429.
Write down 8 as next digit of the result. 
Result so far: 88.0
Deduct 7840 from 8269 and we're left with 429.
Take the next digit (0) from the dividend and append it to 429, then repeat: 4290 / 980

Moving on to step 6:
The number 980 fits into 4290 4 times, leaving a remainder of 370.
Record the quotient 4 as the next digit in the result. 
Result so far: 884.0
If we take 3920 away from 4290, we end up with 370.
Bring next digit (3) of the dividend behind the 370 and repeat the process: 3703 / 980

Moving on to step 7:
When dividing 3703 by 980, we get 3 with a remainder of 763.
The next digit of our result is 3. 
Result so far: 8843.0
Subtract 2940 from 3703 to get 763.
Fetch the next digit (9) from the dividend, attach it to 763 and continue: 7639 / 980

Moving on to step 8:
980 can be fit into 7639 7 times, resulting in a remainder of 779.
The number 7 becomes the next digit in our result. 
Result so far: 88437.0
If we take 6860 away from 7639, we end up with 779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7790, and continue the process.

Advancing to step 9:
980 goes into 7790 7 times with a remainder of 930.
Record the quotient 7 as the next digit in the result. 
Result so far: 88437.7
Subtract 6860 from 7790 to get 930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9300, and continue the process.

Going ahead to step 10:
980 can be fit into 9300 9 times, resulting in a remainder of 480.
Put 9 as the next digit of the answer. 
Result so far: 88437.79
If we take 8820 away from 9300, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 11:
980 goes into 4800 4 times with a remainder of 880.
Record the quotient 4 as the next digit in the result. 
Result so far: 88437.794
Deduct 3920 from 4800 and we're left with 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

On to step 12:
When dividing 8800 by 980, we get 8 with a remainder of 960.
The number 8 becomes the next digit in our result. 
Result so far: 88437.7948
The remainder is 960 after subtracting 7840 from 8800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9600, and continue the process.

Step 13:
980 goes into 9600 9 times with a remainder of 780.
Use 9 as the next digit of our solution. 
Result so far: 88437.79489
The remainder is 780 after subtracting 8820 from 9600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

On to step 14:
When dividing 7800 by 980, we get 7 with a remainder of 940.
Put 7 as the next digit of the answer. 
Result so far: 88437.794897
If we subtract 6860 from 7800, we get 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

Let's proceed to step 15:
When dividing 9400 by 980, we get 9 with a remainder of 580.
The next digit of our result is 9. 
Result so far: 88437.7948979
If we subtract 8820 from 9400, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 16:
980 goes into 5800 5 times with a remainder of 900.
Record the quotient 5 as the next digit in the result. 
Result so far: 88437.79489795
Subtract 4900 from 5800 to get 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Our division results in 88437.79489795 with a remaining 9e-07.
