We're dividing 83490105 by 637 
We want to divide 83490105 by 637.

Going ahead to step 1:
8 divided by 637 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 637

Going ahead to step 2:
If we divide 83 by 637, we get 0 and a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Include the next digit (4) from the dividend after 83, then repeat: 834 / 637

On to step 3:
637 goes into 834 1 times with a remainder of 197.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 637 from 834 leaves us with 197.
Bring next digit (9) of the dividend behind the 197 and repeat the process: 1979 / 637

Let's proceed to step 4:
The number 637 fits into 1979 3 times, leaving a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 1911 from 1979, we get 68.
Fetch the next digit (0) from the dividend, attach it to 68 and continue: 680 / 637

Step 5:
680 divided by 637 is 1 with a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 131.0
Deduct 637 from 680 and we're left with 43.
Take the next digit (1) from the dividend and append it to 43, then repeat: 431 / 637

Let's proceed to step 6:
When dividing 431 by 637, we get 0 with a remainder of 431.
Use 0 as the next digit of our solution. 
Result so far: 1310.0
Subtracting 0 from 431 leaves us with 431.
Take the next digit (0) from the dividend and append it to 431, then repeat: 4310 / 637

Let's proceed to step 7:
When dividing 4310 by 637, we get 6 with a remainder of 488.
The next digit of our result is 6. 
Result so far: 13106.0
If we subtract 3822 from 4310, we get 488.
Bring next digit (5) of the dividend behind the 488 and repeat the process: 4885 / 637

Let's proceed to step 8:
If we divide 4885 by 637, we get 7 and a remainder of 426.
The number 7 becomes the next digit in our result. 
Result so far: 131067.0
Subtract 4459 from 4885 to get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Moving on to step 9:
4260 divided by 637 is 6 with a remainder of 438.
The next digit of our result is 6. 
Result so far: 131067.6
If we take 3822 away from 4260, we end up with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Moving on to step 10:
If we divide 4380 by 637, we get 6 and a remainder of 558.
The number 6 becomes the next digit in our result. 
Result so far: 131067.66
Subtract 3822 from 4380 to get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

The quotient of the division is 131067.66, and the remainder is 0.558.
