We're dividing 70510393 by 316 
We want to figure out the number of times 70510393 can be divided by 316.

On to step 1:
316 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 316

Let's proceed to step 2:
316 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Grab the next digit (5) from the dividend, add it to 70, then carry on: 705 / 316

Going ahead to step 3:
316 can be fit into 705 2 times, resulting in a remainder of 73.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 632 from 705 and we're left with 73.
Append the next digit (1) from the dividend to 73 and continue with: 731 / 316

On to step 4:
731 divided by 316 is 2 with a remainder of 99.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtracting 632 from 731 leaves us with 99.
Take the next digit (0) from the dividend and append it to 99, then repeat: 990 / 316

Moving on to step 5:
990 divided by 316 is 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 223.0
Subtracting 948 from 990 leaves us with 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 316

On to step 6:
316 can be fit into 423 1 times, resulting in a remainder of 107.
Use 1 as the next digit of our solution. 
Result so far: 2231.0
If we take 316 away from 423, we end up with 107.
Append the next digit (9) from the dividend to 107 and continue with: 1079 / 316

Going ahead to step 7:
316 goes into 1079 3 times with a remainder of 131.
Use 3 as the next digit of our solution. 
Result so far: 22313.0
Deduct 948 from 1079 and we're left with 131.
Grab the next digit (3) from the dividend, add it to 131, then carry on: 1313 / 316

Step 8:
316 can be fit into 1313 4 times, resulting in a remainder of 49.
Use 4 as the next digit of our solution. 
Result so far: 223134.0
Subtract 1264 from 1313 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
316 can be fit into 490 1 times, resulting in a remainder of 174.
The next digit of our result is 1. 
Result so far: 223134.1
The remainder is 174 after subtracting 316 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 10:
When dividing 1740 by 316, we get 5 with a remainder of 160.
Put 5 as the next digit of the answer. 
Result so far: 223134.15
Subtracting 1580 from 1740 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 11:
1600 divided by 316 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 223134.155
Subtract 1580 from 1600 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 223134.155, and the remainder is 0.002.
