640126 divided by 89 
Our goal is to divide 640126 by 89.

On to step 1:
6 divided by 89 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 89

Let's proceed to step 2:
89 goes into 64 0 times with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 89

On to step 3:
The number 89 fits into 640 7 times, leaving a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 623 from 640, we get 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 89

Going ahead to step 4:
If we divide 171 by 89, we get 1 and a remainder of 82.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
If we subtract 89 from 171, we get 82.
Include the next digit (2) from the dividend after 82, then repeat: 822 / 89

Going ahead to step 5:
89 can be fit into 822 9 times, resulting in a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 719.0
Subtract 801 from 822 to get 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 89

Advancing to step 6:
When dividing 216 by 89, we get 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 7192.0
Deduct 178 from 216 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
380 divided by 89 is 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 7192.4
Subtract 356 from 380 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
The number 89 fits into 240 2 times, leaving a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 7192.42
If we take 178 away from 240, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 9:
89 can be fit into 620 6 times, resulting in a remainder of 86.
Write down 6 as next digit of the result. 
Result so far: 7192.426
Subtracting 534 from 620 leaves us 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.

On to step 10:
89 can be fit into 860 9 times, resulting in a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 7192.4269
If we subtract 801 from 860, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 11:
If we divide 590 by 89, we get 6 and a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 7192.42696
If we take 534 away from 590, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
The number 89 fits into 560 6 times, leaving a remainder of 26.
The next digit of our result is 6. 
Result so far: 7192.426966
Subtract 534 from 560 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 7192.426966, with a leftover of 2.6e-06.
