87400270 ÷ 606 
Our goal is to divide 87400270 by 606.

Let's proceed to step 1:
When dividing 8 by 606, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 606

On to step 2:
The number 606 fits into 87 0 times, leaving a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Append the next digit (4) from the dividend to 87 and continue with: 874 / 606

Let's proceed to step 3:
874 divided by 606 is 1 with a remainder of 268.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 606 away from 874, we end up with 268.
Append the next digit (0) from the dividend to 268 and continue with: 2680 / 606

Let's proceed to step 4:
2680 divided by 606 is 4 with a remainder of 256.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 2424 from 2680 to get 256.
Fetch the next digit (0) from the dividend, attach it to 256 and continue: 2560 / 606

Moving on to step 5:
606 can be fit into 2560 4 times, resulting in a remainder of 136.
Write down 4 as next digit of the result. 
Result so far: 144.0
Subtract 2424 from 2560 to get 136.
Append the next digit (2) from the dividend to 136 and continue with: 1362 / 606

Let's proceed to step 6:
606 can be fit into 1362 2 times, resulting in a remainder of 150.
The number 2 becomes the next digit in our result. 
Result so far: 1442.0
Deduct 1212 from 1362 and we're left with 150.
Take the next digit (7) from the dividend and append it to 150, then repeat: 1507 / 606

Let's proceed to step 7:
1507 divided by 606 is 2 with a remainder of 295.
The next digit of our result is 2. 
Result so far: 14422.0
If we take 1212 away from 1507, we end up with 295.
Fetch the next digit (0) from the dividend, attach it to 295 and continue: 2950 / 606

Let's proceed to step 8:
If we divide 2950 by 606, we get 4 and a remainder of 526.
Write down 4 as next digit of the result. 
Result so far: 144224.0
Subtracting 2424 from 2950 leaves us with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Step 9:
606 goes into 5260 8 times with a remainder of 412.
The number 8 becomes the next digit in our result. 
Result so far: 144224.8
Subtracting 4848 from 5260 leaves us with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Moving on to step 10:
When dividing 4120 by 606, we get 6 with a remainder of 484.
Use 6 as the next digit of our solution. 
Result so far: 144224.86
The remainder is 484 after subtracting 3636 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Going ahead to step 11:
The number 606 fits into 4840 7 times, leaving a remainder of 598.
Put 7 as the next digit of the answer. 
Result so far: 144224.867
Subtracting 4242 from 4840 leaves us with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

On to step 12:
When dividing 5980 by 606, we get 9 with a remainder of 526.
The next digit of our result is 9. 
Result so far: 144224.8679
Subtracting 5454 from 5980 leaves us with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Going ahead to step 13:
If we divide 5260 by 606, we get 8 and a remainder of 412.
The number 8 becomes the next digit in our result. 
Result so far: 144224.86798
Deduct 4848 from 5260 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Let's proceed to step 14:
4120 divided by 606 is 6 with a remainder of 484.
Write down 6 as next digit of the result. 
Result so far: 144224.867986
If we take 3636 away from 4120, we end up with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Step 15:
606 goes into 4840 7 times with a remainder of 598.
The next digit of our result is 7. 
Result so far: 144224.8679867
Deduct 4242 from 4840 and we're left with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Let's proceed to step 16:
606 goes into 5980 9 times with a remainder of 526.
Use 9 as the next digit of our solution. 
Result so far: 144224.86798679
Deduct 5454 from 5980 and we're left with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

The final outcome is 144224.86798679, with a leftover of 5.26e-07.
