89686503 ÷ 170 
We want to figure out the number of times 89686503 can be divided by 170.

Moving on to step 1:
If we divide 8 by 170, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 170

Let's proceed to step 2:
If we divide 89 by 170, we get 0 and a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Fetch the next digit (6) from the dividend, attach it to 89 and continue: 896 / 170

On to step 3:
If we divide 896 by 170, we get 5 and a remainder of 46.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 46 after subtracting 850 from 896.
Append the next digit (8) from the dividend to 46 and continue with: 468 / 170

Moving on to step 4:
If we divide 468 by 170, we get 2 and a remainder of 128.
The next digit of our result is 2. 
Result so far: 52.0
The remainder is 128 after subtracting 340 from 468.
Grab the next digit (6) from the dividend, add it to 128, then carry on: 1286 / 170

Step 5:
170 can be fit into 1286 7 times, resulting in a remainder of 96.
Put 7 as the next digit of the answer. 
Result so far: 527.0
Deduct 1190 from 1286 and we're left with 96.
Take the next digit (5) from the dividend and append it to 96, then repeat: 965 / 170

Advancing to step 6:
170 can be fit into 965 5 times, resulting in a remainder of 115.
The number 5 becomes the next digit in our result. 
Result so far: 5275.0
Subtract 850 from 965 to get 115.
Fetch the next digit (0) from the dividend, attach it to 115 and continue: 1150 / 170

Let's proceed to step 7:
When dividing 1150 by 170, we get 6 with a remainder of 130.
Put 6 as the next digit of the answer. 
Result so far: 52756.0
Subtracting 1020 from 1150 leaves us with 130.
Fetch the next digit (3) from the dividend, attach it to 130 and continue: 1303 / 170

Step 8:
1303 divided by 170 is 7 with a remainder of 113.
Use 7 as the next digit of our solution. 
Result so far: 527567.0
The remainder is 113 after subtracting 1190 from 1303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 9:
1130 divided by 170 is 6 with a remainder of 110.
Put 6 as the next digit of the answer. 
Result so far: 527567.6
If we subtract 1020 from 1130, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
If we divide 1100 by 170, we get 6 and a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 527567.66
Subtract 1020 from 1100 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 527567.66, and the remainder is 0.08.
