We're dividing 90300419 by 670 
Let's see how many times 670 fits into 90300419.

On to step 1:
When dividing 9 by 670, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 670

Moving on to step 2:
90 divided by 670 is 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Fetch the next digit (3) from the dividend, attach it to 90 and continue: 903 / 670

Going ahead to step 3:
The number 670 fits into 903 1 times, leaving a remainder of 233.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 670 from 903, we get 233.
Take the next digit (0) from the dividend and append it to 233, then repeat: 2330 / 670

Going ahead to step 4:
2330 divided by 670 is 3 with a remainder of 320.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 2010 from 2330 and we're left with 320.
Append the next digit (0) from the dividend to 320 and continue with: 3200 / 670

Let's proceed to step 5:
The number 670 fits into 3200 4 times, leaving a remainder of 520.
Write down 4 as next digit of the result. 
Result so far: 134.0
Subtracting 2680 from 3200 leaves us with 520.
Fetch the next digit (4) from the dividend, attach it to 520 and continue: 5204 / 670

Going ahead to step 6:
The number 670 fits into 5204 7 times, leaving a remainder of 514.
The number 7 becomes the next digit in our result. 
Result so far: 1347.0
If we take 4690 away from 5204, we end up with 514.
Append the next digit (1) from the dividend to 514 and continue with: 5141 / 670

Step 7:
When dividing 5141 by 670, we get 7 with a remainder of 451.
The next digit of our result is 7. 
Result so far: 13477.0
Subtracting 4690 from 5141 leaves us with 451.
Fetch the next digit (9) from the dividend, attach it to 451 and continue: 4519 / 670

Moving on to step 8:
The number 670 fits into 4519 6 times, leaving a remainder of 499.
The next digit of our result is 6. 
Result so far: 134776.0
If we subtract 4020 from 4519, we get 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Moving on to step 9:
When dividing 4990 by 670, we get 7 with a remainder of 300.
Write down 7 as next digit of the result. 
Result so far: 134776.7
If we take 4690 away from 4990, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 10:
670 goes into 3000 4 times with a remainder of 320.
Write down 4 as next digit of the result. 
Result so far: 134776.74
If we take 2680 away from 3000, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 11:
The number 670 fits into 3200 4 times, leaving a remainder of 520.
The number 4 becomes the next digit in our result. 
Result so far: 134776.744
The remainder is 520 after subtracting 2680 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

The final outcome is 134776.744, with a leftover of 0.052.
