We're dividing 66889734 by 70 
We're looking to find how many times 70 goes into 66889734.

Moving on to step 1:
If we divide 6 by 70, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 70

Going ahead to step 2:
When dividing 66 by 70, we get 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 70

Step 3:
668 divided by 70 is 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 630 from 668 leaves us with 38.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 70

On to step 4:
70 goes into 388 5 times with a remainder of 38.
The next digit of our result is 5. 
Result so far: 95.0
If we subtract 350 from 388, we get 38.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 70

Let's proceed to step 5:
If we divide 389 by 70, we get 5 and a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 955.0
Deduct 350 from 389 and we're left with 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 70

Let's proceed to step 6:
397 divided by 70 is 5 with a remainder of 47.
Write down 5 as next digit of the result. 
Result so far: 9555.0
Subtracting 350 from 397 leaves us with 47.
Bring next digit (3) of the dividend behind the 47 and repeat the process: 473 / 70

Moving on to step 7:
70 can be fit into 473 6 times, resulting in a remainder of 53.
Use 6 as the next digit of our solution. 
Result so far: 95556.0
The remainder is 53 after subtracting 420 from 473.
Append the next digit (4) from the dividend to 53 and continue with: 534 / 70

On to step 8:
70 can be fit into 534 7 times, resulting in a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 955567.0
Subtract 490 from 534 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
70 goes into 440 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 955567.6
Subtracting 420 from 440 leaves us 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.

Going ahead to step 10:
70 goes into 200 2 times with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 955567.62
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.

Moving on to step 11:
600 divided by 70 is 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 955567.628
Deduct 560 from 600 and we're left with 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 12:
The number 70 fits into 400 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 955567.6285
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.

Going ahead to step 13:
When dividing 500 by 70, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 955567.62857
Subtracting 490 from 500 leaves us 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 14:
If we divide 100 by 70, we get 1 and a remainder of 30.
The next digit of our result is 1. 
Result so far: 955567.628571
Deduct 70 from 100 and we're left 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.

Advancing to step 15:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 955567.6285714
If we subtract 280 from 300, we 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.

On to step 16:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 955567.62857142
Deduct 140 from 200 and we're left 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.

The final outcome is 955567.62857142, with a leftover of 6e-08.
