We divide 81644346 by 70
Our goal is to divide 81644346 by 70.

Moving on to step 1:
70 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 70

Going ahead to step 2:
When dividing 81 by 70, we get 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 11 after subtracting 70 from 81.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 70

Advancing to step 3:
The number 70 fits into 116 1 times, leaving a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 70 from 116 and we're left with 46.
Bring next digit (4) of the dividend behind the 46 and repeat the process: 464 / 70

Going ahead to step 4:
70 can be fit into 464 6 times, resulting in a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
The remainder is 44 after subtracting 420 from 464.
Include the next digit (4) from the dividend after 44, then repeat: 444 / 70

Advancing to step 5:
70 goes into 444 6 times with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 1166.0
If we subtract 420 from 444, we get 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 70

Let's proceed to step 6:
The number 70 fits into 243 3 times, leaving a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 11663.0
If we subtract 210 from 243, we get 33.
Take the next digit (4) from the dividend and append it to 33, then repeat: 334 / 70

Going ahead to step 7:
70 goes into 334 4 times with a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 116634.0
Subtracting 280 from 334 leaves us with 54.
Include the next digit (6) from the dividend after 54, then repeat: 546 / 70

Let's proceed to step 8:
If we divide 546 by 70, we get 7 and a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 1166347.0
If we subtract 490 from 546, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
70 can be fit into 560 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 1166347.8
Deduct 560 from 560 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
When dividing 0 by 70, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1166347.8
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
If we divide 0 by 70, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1166347.8
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 1166347.8 with a remaining 0.0.
