We're dividing 70521986 by 419 
We want to figure out the number of times 70521986 can be divided by 419.

Going ahead to step 1:
If we divide 7 by 419, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 419

Let's proceed to step 2:
419 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Take the next digit (5) from the dividend and append it to 70, then repeat: 705 / 419

Moving on to step 3:
The number 419 fits into 705 1 times, leaving a remainder of 286.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 286 after subtracting 419 from 705.
Bring next digit (2) of the dividend behind the 286 and repeat the process: 2862 / 419

Moving on to step 4:
419 can be fit into 2862 6 times, resulting in a remainder of 348.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 2514 from 2862 to get 348.
Take the next digit (1) from the dividend and append it to 348, then repeat: 3481 / 419

Step 5:
If we divide 3481 by 419, we get 8 and a remainder of 129.
Record the quotient 8 as the next digit in the result. 
Result so far: 168.0
If we take 3352 away from 3481, we end up with 129.
Take the next digit (9) from the dividend and append it to 129, then repeat: 1299 / 419

Let's proceed to step 6:
The number 419 fits into 1299 3 times, leaving a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 1683.0
Subtracting 1257 from 1299 leaves us with 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 419

Let's proceed to step 7:
The number 419 fits into 428 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 16831.0
The remainder is 9 after subtracting 419 from 428.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 419

Advancing to step 8:
419 goes into 96 0 times with a remainder of 96.
The number 0 becomes the next digit in our result. 
Result so far: 168310.0
The remainder is 96 after subtracting 0 from 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 9:
960 divided by 419 is 2 with a remainder of 122.
Put 2 as the next digit of the answer. 
Result so far: 168310.2
The remainder is 122 after subtracting 838 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 10:
419 can be fit into 1220 2 times, resulting in a remainder of 382.
Record the quotient 2 as the next digit in the result. 
Result so far: 168310.22
If we subtract 838 from 1220, we get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

After the division, we end up with 168310.22 and a remainder of 0.382.
