We're dividing 90457864 by 670 
Our goal is to divide 90457864 by 670.

On to step 1:
When dividing 9 by 670, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 670

Going ahead to step 2:
The number 670 fits into 90 0 times, leaving a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Include the next digit (4) from the dividend after 90, then repeat: 904 / 670

Let's proceed to step 3:
The number 670 fits into 904 1 times, leaving a remainder of 234.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 670 from 904 to get 234.
Include the next digit (5) from the dividend after 234, then repeat: 2345 / 670

Moving on to step 4:
When dividing 2345 by 670, we get 3 with a remainder of 335.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 2010 from 2345 to get 335.
Fetch the next digit (7) from the dividend, attach it to 335 and continue: 3357 / 670

Step 5:
670 can be fit into 3357 5 times, resulting in a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 135.0
Subtract 3350 from 3357 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 670

Advancing to step 6:
If we divide 78 by 670, we get 0 and a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 1350.0
If we subtract 0 from 78, we get 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 670

Step 7:
The number 670 fits into 786 1 times, leaving a remainder of 116.
The next digit of our result is 1. 
Result so far: 13501.0
Deduct 670 from 786 and we're left with 116.
Include the next digit (4) from the dividend after 116, then repeat: 1164 / 670

Advancing to step 8:
1164 divided by 670 is 1 with a remainder of 494.
Record the quotient 1 as the next digit in the result. 
Result so far: 135011.0
If we take 670 away from 1164, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Step 9:
4940 divided by 670 is 7 with a remainder of 250.
Write down 7 as next digit of the result. 
Result so far: 135011.7
Deduct 4690 from 4940 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 10:
670 can be fit into 2500 3 times, resulting in a remainder of 490.
Write down 3 as next digit of the result. 
Result so far: 135011.73
If we take 2010 away from 2500, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 11:
When dividing 4900 by 670, we get 7 with a remainder of 210.
Use 7 as the next digit of our solution. 
Result so far: 135011.737
Subtracting 4690 from 4900 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 12:
670 goes into 2100 3 times with a remainder of 90.
Put 3 as the next digit of the answer. 
Result so far: 135011.7373
Subtract 2010 from 2100 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 13:
The number 670 fits into 900 1 times, leaving a remainder of 230.
Record the quotient 1 as the next digit in the result. 
Result so far: 135011.73731
Deduct 670 from 900 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 14:
If we divide 2300 by 670, we get 3 and a remainder of 290.
Record the quotient 3 as the next digit in the result. 
Result so far: 135011.737313
The remainder is 290 after subtracting 2010 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 15:
2900 divided by 670 is 4 with a remainder of 220.
Record the quotient 4 as the next digit in the result. 
Result so far: 135011.7373134
Subtract 2680 from 2900 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 16:
When dividing 2200 by 670, we get 3 with a remainder of 190.
Put 3 as the next digit of the answer. 
Result so far: 135011.73731343
Subtract 2010 from 2200 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The final outcome is 135011.73731343, with a leftover of 1.9e-07.
