877255 ÷ 70 
We want to figure out the number of times 877255 can be divided by 70.

On to step 1:
When dividing 8 by 70, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 70

Moving on to step 2:
When dividing 87 by 70, we get 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 17 after subtracting 70 from 87.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 70

Step 3:
If we divide 177 by 70, we get 2 and a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 140 from 177 leaves us with 37.
Append the next digit (2) from the dividend to 37 and continue with: 372 / 70

Advancing to step 4:
70 goes into 372 5 times with a remainder of 22.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
If we take 350 away from 372, we end up with 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 70

Let's proceed to step 5:
If we divide 225 by 70, we get 3 and a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 1253.0
Subtracting 210 from 225 leaves us with 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 70

Moving on to step 6:
When dividing 155 by 70, we get 2 with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 12532.0
Subtract 140 from 155 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
When dividing 150 by 70, we get 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 12532.2
Subtract 140 from 150 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 12532.21
Subtract 70 from 100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
If we divide 300 by 70, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 12532.214
If we take 280 away from 300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 12532.2142
Subtracting 140 from 200 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 12532.21428
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
When dividing 400 by 70, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 12532.214285
Deduct 350 from 400 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
The number 70 fits into 500 7 times, leaving a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 12532.2142857
If we subtract 490 from 500, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
When dividing 100 by 70, we get 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 12532.21428571
Subtracting 70 from 100 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 12532.21428571, with a leftover of 3e-08.
