We divide 70089087 by 642
Let's see how many times 642 fits into 70089087.

Let's proceed to step 1:
When dividing 7 by 642, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 642

Going ahead to step 2:
642 can be fit into 70 0 times, resulting in a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Bring next digit (0) of the dividend behind the 70 and repeat the process: 700 / 642

Step 3:
642 goes into 700 1 times with a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 642 from 700 and we're left with 58.
Grab the next digit (8) from the dividend, add it to 58, then carry on: 588 / 642

Moving on to step 4:
The number 642 fits into 588 0 times, leaving a remainder of 588.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 588, we get 588.
Take the next digit (9) from the dividend and append it to 588, then repeat: 5889 / 642

Advancing to step 5:
The number 642 fits into 5889 9 times, leaving a remainder of 111.
The next digit of our result is 9. 
Result so far: 109.0
The remainder is 111 after subtracting 5778 from 5889.
Take the next digit (0) from the dividend and append it to 111, then repeat: 1110 / 642

On to step 6:
1110 divided by 642 is 1 with a remainder of 468.
Write down 1 as next digit of the result. 
Result so far: 1091.0
If we subtract 642 from 1110, we get 468.
Bring next digit (8) of the dividend behind the 468 and repeat the process: 4688 / 642

Step 7:
If we divide 4688 by 642, we get 7 and a remainder of 194.
Write down 7 as next digit of the result. 
Result so far: 10917.0
If we subtract 4494 from 4688, we get 194.
Take the next digit (7) from the dividend and append it to 194, then repeat: 1947 / 642

Moving on to step 8:
If we divide 1947 by 642, we get 3 and a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 109173.0
If we take 1926 away from 1947, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 9:
210 divided by 642 is 0 with a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 109173.0
If we take 0 away from 210, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 10:
If we divide 2100 by 642, we get 3 and a remainder of 174.
Put 3 as the next digit of the answer. 
Result so far: 109173.03
Deduct 1926 from 2100 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 11:
642 goes into 1740 2 times with a remainder of 456.
The next digit of our result is 2. 
Result so far: 109173.032
Deduct 1284 from 1740 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Let's proceed to step 12:
If we divide 4560 by 642, we get 7 and a remainder of 66.
Put 7 as the next digit of the answer. 
Result so far: 109173.0327
Subtract 4494 from 4560 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 13:
660 divided by 642 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 109173.03271
If we take 642 away from 660, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 14:
642 goes into 180 0 times with a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 109173.03271
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 15:
642 goes into 1800 2 times with a remainder of 516.
Put 2 as the next digit of the answer. 
Result so far: 109173.0327102
If we take 1284 away from 1800, we end up with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Let's proceed to step 16:
642 goes into 5160 8 times with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 109173.03271028
If we subtract 5136 from 5160, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 109173.03271028, with a leftover of 2.4e-08.
