We divide 51689489 by 168
We want to divide 51689489 by 168.

Let's proceed to step 1:
When dividing 5 by 168, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 168

Advancing to step 2:
The number 168 fits into 51 0 times, leaving a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Include the next digit (6) from the dividend after 51, then repeat: 516 / 168

Step 3:
When dividing 516 by 168, we get 3 with a remainder of 12.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 12 after subtracting 504 from 516.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 168

On to step 4:
128 divided by 168 is 0 with a remainder of 128.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we subtract 0 from 128, we get 128.
Bring next digit (9) of the dividend behind the 128 and repeat the process: 1289 / 168

Advancing to step 5:
The number 168 fits into 1289 7 times, leaving a remainder of 113.
Use 7 as the next digit of our solution. 
Result so far: 307.0
The remainder is 113 after subtracting 1176 from 1289.
Include the next digit (4) from the dividend after 113, then repeat: 1134 / 168

Step 6:
168 can be fit into 1134 6 times, resulting in a remainder of 126.
Record the quotient 6 as the next digit in the result. 
Result so far: 3076.0
Subtract 1008 from 1134 to get 126.
Take the next digit (8) from the dividend and append it to 126, then repeat: 1268 / 168

Going ahead to step 7:
The number 168 fits into 1268 7 times, leaving a remainder of 92.
Use 7 as the next digit of our solution. 
Result so far: 30767.0
If we take 1176 away from 1268, we end up with 92.
Bring next digit (9) of the dividend behind the 92 and repeat the process: 929 / 168

Let's proceed to step 8:
929 divided by 168 is 5 with a remainder of 89.
The number 5 becomes the next digit in our result. 
Result so far: 307675.0
Deduct 840 from 929 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 9:
The number 168 fits into 890 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 307675.5
Deduct 840 from 890 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
If we divide 500 by 168, we get 2 and a remainder of 164.
Record the quotient 2 as the next digit in the result. 
Result so far: 307675.52
Subtract 336 from 500 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 11:
1640 divided by 168 is 9 with a remainder of 128.
Record the quotient 9 as the next digit in the result. 
Result so far: 307675.529
Subtract 1512 from 1640 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 12:
The number 168 fits into 1280 7 times, leaving a remainder of 104.
Use 7 as the next digit of our solution. 
Result so far: 307675.5297
Subtracting 1176 from 1280 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 13:
When dividing 1040 by 168, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 307675.52976
The remainder is 32 after subtracting 1008 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
When dividing 320 by 168, we get 1 with a remainder of 152.
The next digit of our result is 1. 
Result so far: 307675.529761
Subtract 168 from 320 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 15:
168 can be fit into 1520 9 times, resulting in a remainder of 8.
The next digit of our result is 9. 
Result so far: 307675.5297619
Subtract 1512 from 1520 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 16:
80 divided by 168 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 307675.5297619
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 307675.5297619, with a leftover of 8e-08.
