Let's divide 21738786 by 70
Our goal is to divide 21738786 by 70.

Moving on to step 1:
When dividing 2 by 70, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 70

Advancing to step 2:
When dividing 21 by 70, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 70

Let's proceed to step 3:
217 divided by 70 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 210 from 217 and we're left with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 70

Advancing to step 4:
73 divided by 70 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtracting 70 from 73 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 70

On to step 5:
70 goes into 38 0 times with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 310.0
Deduct 0 from 38 and we're left with 38.
Take the next digit (7) from the dividend and append it to 38, then repeat: 387 / 70

Step 6:
If we divide 387 by 70, we get 5 and a remainder of 37.
The next digit of our result is 5. 
Result so far: 3105.0
The remainder is 37 after subtracting 350 from 387.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 70

On to step 7:
70 goes into 378 5 times with a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 31055.0
Deduct 350 from 378 and we're left with 28.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 70

On to step 8:
70 goes into 286 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 310554.0
Subtract 280 from 286 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
70 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 310554.0
If we take 0 away from 60, we end up 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.

Moving on to step 10:
600 divided by 70 is 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 310554.08
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.

Let's proceed to step 11:
70 goes into 400 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 310554.085
If we subtract 350 from 400, we 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.

Let's proceed to step 12:
If we divide 500 by 70, we get 7 and a remainder of 10.
The next digit of our result is 7. 
Result so far: 310554.0857
Deduct 490 from 500 and we're left 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.

Advancing to step 13:
If we divide 100 by 70, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 310554.08571
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 14:
70 goes into 300 4 times with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 310554.085714
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.

On to step 15:
70 goes into 200 2 times with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 310554.0857142
If we take 140 away from 200, we end up 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.

On to step 16:
When dividing 600 by 70, we get 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 310554.08571428
Subtract 560 from 600 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.

The final result is 310554.08571428 with a remainder of 4e-08.
