42891036 divided by 70 
We want to figure out the number of times 42891036 can be divided by 70.

On to step 1:
If we divide 4 by 70, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 70

Step 2:
If we divide 42 by 70, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 70

Let's proceed to step 3:
If we divide 428 by 70, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 420 from 428 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 70

Going ahead to step 4:
When dividing 89 by 70, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 61.0
If we take 70 away from 89, we end up with 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 70

Let's proceed to step 5:
70 can be fit into 191 2 times, resulting in a remainder of 51.
Record the quotient 2 as the next digit in the result. 
Result so far: 612.0
Deduct 140 from 191 and we're left with 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 70

Going ahead to step 6:
When dividing 510 by 70, we get 7 with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 6127.0
The remainder is 20 after subtracting 490 from 510.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 70

Going ahead to step 7:
If we divide 203 by 70, we get 2 and a remainder of 63.
Put 2 as the next digit of the answer. 
Result so far: 61272.0
If we take 140 away from 203, we end up with 63.
Take the next digit (6) from the dividend and append it to 63, then repeat: 636 / 70

Step 8:
70 can be fit into 636 9 times, resulting in a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 612729.0
The remainder is 6 after subtracting 630 from 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
70 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 612729.0
Subtract 0 from 60 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.

Going ahead to step 10:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 612729.08
Subtracting 560 from 600 leaves us 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.

Step 11:
400 divided by 70 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 612729.085
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.

Advancing to step 12:
500 divided by 70 is 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 612729.0857
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 13:
100 divided by 70 is 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 612729.08571
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.

Moving on to step 14:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 612729.085714
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.

Moving on to step 15:
70 can be fit into 200 2 times, resulting in a remainder of 60.
The next digit of our result is 2. 
Result so far: 612729.0857142
Subtracting 140 from 200 leaves us 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.

Let's proceed to step 16:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 612729.08571428
The remainder is 40 after subtracting 560 from 600.
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 612729.08571428 with a remainder of 4e-08.
