81564732 ÷ 70 
Our goal is to divide 81564732 by 70.

Step 1:
70 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 70

Let's proceed to step 2:
70 can be fit into 81 1 times, resulting in a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 70 from 81 leaves us with 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 70

Moving on to step 3:
115 divided by 70 is 1 with a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 70 from 115 and we're left with 45.
Append the next digit (6) from the dividend to 45 and continue with: 456 / 70

Advancing to step 4:
The number 70 fits into 456 6 times, leaving a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 116.0
Subtracting 420 from 456 leaves us with 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 70

Going ahead to step 5:
If we divide 364 by 70, we get 5 and a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 1165.0
Subtracting 350 from 364 leaves us with 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 70

Advancing to step 6:
147 divided by 70 is 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 11652.0
Subtracting 140 from 147 leaves us with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 70

Moving on to step 7:
73 divided by 70 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 116521.0
The remainder is 3 after subtracting 70 from 73.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 70

Advancing to step 8:
The number 70 fits into 32 0 times, leaving a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 1165210.0
If we subtract 0 from 32, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
70 can be fit into 320 4 times, resulting in a remainder of 40.
The next digit of our result is 4. 
Result so far: 1165210.4
Subtract 280 from 320 to 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.

On to step 10:
70 goes into 400 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1165210.45
Subtracting 350 from 400 leaves us 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.

Moving on to step 11:
The number 70 fits into 500 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 1165210.457
If we take 490 away from 500, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
The number 70 fits into 100 1 times, leaving a remainder of 30.
The next digit of our result is 1. 
Result so far: 1165210.4571
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.

Let's proceed to step 13:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 1165210.45714
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 14:
When dividing 200 by 70, we get 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 1165210.457142
Subtract 140 from 200 to get 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 15:
If we divide 600 by 70, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 1165210.4571428
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.

Going ahead to step 16:
When dividing 400 by 70, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 1165210.45714285
Subtract 350 from 400 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 1165210.45714285, with a leftover of 5e-08.
