We're dividing 70185714 by 781 
Our goal is to divide 70185714 by 781.

Step 1:
When dividing 7 by 781, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 781

Moving on to step 2:
781 goes into 70 0 times with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Include the next digit (1) from the dividend after 70, then repeat: 701 / 781

Going ahead to step 3:
701 divided by 781 is 0 with a remainder of 701.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 701 after subtracting 0 from 701.
Append the next digit (8) from the dividend to 701 and continue with: 7018 / 781

Advancing to step 4:
7018 divided by 781 is 8 with a remainder of 770.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 6248 from 7018 leaves us with 770.
Take the next digit (5) from the dividend and append it to 770, then repeat: 7705 / 781

Advancing to step 5:
7705 divided by 781 is 9 with a remainder of 676.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
Subtracting 7029 from 7705 leaves us with 676.
Take the next digit (7) from the dividend and append it to 676, then repeat: 6767 / 781

On to step 6:
When dividing 6767 by 781, we get 8 with a remainder of 519.
Use 8 as the next digit of our solution. 
Result so far: 898.0
Subtracting 6248 from 6767 leaves us with 519.
Append the next digit (1) from the dividend to 519 and continue with: 5191 / 781

Advancing to step 7:
If we divide 5191 by 781, we get 6 and a remainder of 505.
Use 6 as the next digit of our solution. 
Result so far: 8986.0
Deduct 4686 from 5191 and we're left with 505.
Bring next digit (4) of the dividend behind the 505 and repeat the process: 5054 / 781

On to step 8:
The number 781 fits into 5054 6 times, leaving a remainder of 368.
Use 6 as the next digit of our solution. 
Result so far: 89866.0
If we subtract 4686 from 5054, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 9:
When dividing 3680 by 781, we get 4 with a remainder of 556.
The number 4 becomes the next digit in our result. 
Result so far: 89866.4
Subtracting 3124 from 3680 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Advancing to step 10:
781 can be fit into 5560 7 times, resulting in a remainder of 93.
Use 7 as the next digit of our solution. 
Result so far: 89866.47
If we subtract 5467 from 5560, we get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 11:
781 can be fit into 930 1 times, resulting in a remainder of 149.
Use 1 as the next digit of our solution. 
Result so far: 89866.471
Deduct 781 from 930 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 12:
781 goes into 1490 1 times with a remainder of 709.
Put 1 as the next digit of the answer. 
Result so far: 89866.4711
If we subtract 781 from 1490, we get 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

The final outcome is 89866.4711, with a leftover of 0.00709.
