83900603 divided by 168 
We're looking to find how many times 168 goes into 83900603.

Going ahead to step 1:
If we divide 8 by 168, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 168

Let's proceed to step 2:
When dividing 83 by 168, we get 0 with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Take the next digit (9) from the dividend and append it to 83, then repeat: 839 / 168

Let's proceed to step 3:
If we divide 839 by 168, we get 4 and a remainder of 167.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 672 from 839 to get 167.
Fetch the next digit (0) from the dividend, attach it to 167 and continue: 1670 / 168

Let's proceed to step 4:
1670 divided by 168 is 9 with a remainder of 158.
Put 9 as the next digit of the answer. 
Result so far: 49.0
Subtract 1512 from 1670 to get 158.
Append the next digit (0) from the dividend to 158 and continue with: 1580 / 168

Going ahead to step 5:
1580 divided by 168 is 9 with a remainder of 68.
The number 9 becomes the next digit in our result. 
Result so far: 499.0
Subtracting 1512 from 1580 leaves us with 68.
Include the next digit (6) from the dividend after 68, then repeat: 686 / 168

Moving on to step 6:
If we divide 686 by 168, we get 4 and a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 4994.0
Subtracting 672 from 686 leaves us with 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 168

Step 7:
168 goes into 140 0 times with a remainder of 140.
The next digit of our result is 0. 
Result so far: 49940.0
If we take 0 away from 140, we end up with 140.
Take the next digit (3) from the dividend and append it to 140, then repeat: 1403 / 168

Going ahead to step 8:
If we divide 1403 by 168, we get 8 and a remainder of 59.
Write down 8 as next digit of the result. 
Result so far: 499408.0
The remainder is 59 after subtracting 1344 from 1403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 9:
When dividing 590 by 168, we get 3 with a remainder of 86.
Write down 3 as next digit of the result. 
Result so far: 499408.3
Deduct 504 from 590 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 10:
168 can be fit into 860 5 times, resulting in a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 499408.35
Deduct 840 from 860 and we're left 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 11:
If we divide 200 by 168, we get 1 and a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 499408.351
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
168 can be fit into 320 1 times, resulting in a remainder of 152.
The number 1 becomes the next digit in our result. 
Result so far: 499408.3511
Deduct 168 from 320 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

After the division, we end up with 499408.3511 and a remainder of 0.00152.
