We look at the division of 69577589 by 861 
We want to divide 69577589 by 861.

Going ahead to step 1:
861 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 861

Step 2:
861 can be fit into 69 0 times, resulting in a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Take the next digit (5) from the dividend and append it to 69, then repeat: 695 / 861

Step 3:
If we divide 695 by 861, we get 0 and a remainder of 695.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 695, we get 695.
Grab the next digit (7) from the dividend, add it to 695, then carry on: 6957 / 861

On to step 4:
861 goes into 6957 8 times with a remainder of 69.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 69 after subtracting 6888 from 6957.
Include the next digit (7) from the dividend after 69, then repeat: 697 / 861

Step 5:
861 goes into 697 0 times with a remainder of 697.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtract 0 from 697 to get 697.
Include the next digit (5) from the dividend after 697, then repeat: 6975 / 861

Let's proceed to step 6:
861 goes into 6975 8 times with a remainder of 87.
Put 8 as the next digit of the answer. 
Result so far: 808.0
If we subtract 6888 from 6975, we get 87.
Include the next digit (8) from the dividend after 87, then repeat: 878 / 861

On to step 7:
861 goes into 878 1 times with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 8081.0
The remainder is 17 after subtracting 861 from 878.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 861

Step 8:
179 divided by 861 is 0 with a remainder of 179.
Record the quotient 0 as the next digit in the result. 
Result so far: 80810.0
Deduct 0 from 179 and we're left with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Let's proceed to step 9:
1790 divided by 861 is 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 80810.2
Subtract 1722 from 1790 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 10:
680 divided by 861 is 0 with a remainder of 680.
The number 0 becomes the next digit in our result. 
Result so far: 80810.2
If we take 0 away from 680, we end up with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 11:
6800 divided by 861 is 7 with a remainder of 773.
Put 7 as the next digit of the answer. 
Result so far: 80810.207
If we subtract 6027 from 6800, we get 773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

Let's proceed to step 12:
If we divide 7730 by 861, we get 8 and a remainder of 842.
Use 8 as the next digit of our solution. 
Result so far: 80810.2078
If we take 6888 away from 7730, we end up with 842.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8420, and continue the process.

Going ahead to step 13:
861 goes into 8420 9 times with a remainder of 671.
Put 9 as the next digit of the answer. 
Result so far: 80810.20789
If we take 7749 away from 8420, we end up with 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

Advancing to step 14:
If we divide 6710 by 861, we get 7 and a remainder of 683.
The number 7 becomes the next digit in our result. 
Result so far: 80810.207897
Subtracting 6027 from 6710 leaves us with 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

Advancing to step 15:
The number 861 fits into 6830 7 times, leaving a remainder of 803.
Record the quotient 7 as the next digit in the result. 
Result so far: 80810.2078977
The remainder is 803 after subtracting 6027 from 6830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8030, and continue the process.

The final outcome is 80810.2078977, with a leftover of 8.03e-06.
