We look at the division of 42398485 by 702 
We want to divide 42398485 by 702.

Let's proceed to step 1:
4 divided by 702 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 702

Let's proceed to step 2:
When dividing 42 by 702, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 702

Going ahead to step 3:
The number 702 fits into 423 0 times, leaving a remainder of 423.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 423 and we're left with 423.
Take the next digit (9) from the dividend and append it to 423, then repeat: 4239 / 702

Advancing to step 4:
The number 702 fits into 4239 6 times, leaving a remainder of 27.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 4212 away from 4239, we end up with 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 702

Advancing to step 5:
The number 702 fits into 278 0 times, leaving a remainder of 278.
Put 0 as the next digit of the answer. 
Result so far: 60.0
The remainder is 278 after subtracting 0 from 278.
Fetch the next digit (4) from the dividend, attach it to 278 and continue: 2784 / 702

Advancing to step 6:
702 can be fit into 2784 3 times, resulting in a remainder of 678.
Use 3 as the next digit of our solution. 
Result so far: 603.0
The remainder is 678 after subtracting 2106 from 2784.
Append the next digit (8) from the dividend to 678 and continue with: 6788 / 702

Moving on to step 7:
When dividing 6788 by 702, we get 9 with a remainder of 470.
Put 9 as the next digit of the answer. 
Result so far: 6039.0
Subtract 6318 from 6788 to get 470.
Fetch the next digit (5) from the dividend, attach it to 470 and continue: 4705 / 702

Advancing to step 8:
702 can be fit into 4705 6 times, resulting in a remainder of 493.
Write down 6 as next digit of the result. 
Result so far: 60396.0
Subtract 4212 from 4705 to get 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Going ahead to step 9:
4930 divided by 702 is 7 with a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 60396.7
If we take 4914 away from 4930, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
When dividing 160 by 702, we get 0 with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 60396.7
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
The number 702 fits into 1600 2 times, leaving a remainder of 196.
Put 2 as the next digit of the answer. 
Result so far: 60396.702
The remainder is 196 after subtracting 1404 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 12:
702 goes into 1960 2 times with a remainder of 556.
Record the quotient 2 as the next digit in the result. 
Result so far: 60396.7022
Deduct 1404 from 1960 and we're left with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

The final result is 60396.7022 with a remainder of 0.00556.
