We look at the division of 69891031 by 910 
We want to divide 69891031 by 910.

On to step 1:
When dividing 6 by 910, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 910

On to step 2:
910 goes into 69 0 times with a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Grab the next digit (8) from the dividend, add it to 69, then carry on: 698 / 910

Advancing to step 3:
If we divide 698 by 910, we get 0 and a remainder of 698.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 698 after subtracting 0 from 698.
Append the next digit (9) from the dividend to 698 and continue with: 6989 / 910

Advancing to step 4:
When dividing 6989 by 910, we get 7 with a remainder of 619.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 619 after subtracting 6370 from 6989.
Grab the next digit (1) from the dividend, add it to 619, then carry on: 6191 / 910

Going ahead to step 5:
When dividing 6191 by 910, we get 6 with a remainder of 731.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
If we subtract 5460 from 6191, we get 731.
Append the next digit (0) from the dividend to 731 and continue with: 7310 / 910

Let's proceed to step 6:
910 can be fit into 7310 8 times, resulting in a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 768.0
If we take 7280 away from 7310, we end up with 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 910

Advancing to step 7:
910 can be fit into 303 0 times, resulting in a remainder of 303.
Use 0 as the next digit of our solution. 
Result so far: 7680.0
If we subtract 0 from 303, we get 303.
Append the next digit (1) from the dividend to 303 and continue with: 3031 / 910

Moving on to step 8:
910 can be fit into 3031 3 times, resulting in a remainder of 301.
Write down 3 as next digit of the result. 
Result so far: 76803.0
The remainder is 301 after subtracting 2730 from 3031.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Advancing to step 9:
If we divide 3010 by 910, we get 3 and a remainder of 280.
Use 3 as the next digit of our solution. 
Result so far: 76803.3
Subtracting 2730 from 3010 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 10:
When dividing 2800 by 910, we get 3 with a remainder of 70.
Write down 3 as next digit of the result. 
Result so far: 76803.33
Subtracting 2730 from 2800 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 76803.33, with a leftover of 0.07.
