640162 divided by 91 
We want to divide 640162 by 91.

On to step 1:
91 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 91

Step 2:
If we divide 64 by 91, we get 0 and a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Append the next digit (0) from the dividend to 64 and continue with: 640 / 91

Moving on to step 3:
When dividing 640 by 91, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 7.0
If we take 637 away from 640, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 91

Let's proceed to step 4:
If we divide 31 by 91, we get 0 and a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 70.0
Subtracting 0 from 31 leaves us with 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 91

Going ahead to step 5:
91 can be fit into 316 3 times, resulting in a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 703.0
Subtract 273 from 316 to get 43.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 91

Let's proceed to step 6:
91 goes into 432 4 times with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 7034.0
Deduct 364 from 432 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 7:
When dividing 680 by 91, we get 7 with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 7034.7
If we take 637 away from 680, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 8:
430 divided by 91 is 4 with a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 7034.74
The remainder is 66 after subtracting 364 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 9:
If we divide 660 by 91, we get 7 and a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 7034.747
Subtract 637 from 660 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 10:
91 can be fit into 230 2 times, resulting in a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 7034.7472
The remainder is 48 after subtracting 182 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 11:
480 divided by 91 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 7034.74725
Subtract 455 from 480 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
91 can be fit into 250 2 times, resulting in a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 7034.747252
The remainder is 68 after subtracting 182 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 13:
680 divided by 91 is 7 with a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 7034.7472527
Deduct 637 from 680 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 14:
If we divide 430 by 91, we get 4 and a remainder of 66.
The next digit of our result is 4. 
Result so far: 7034.74725274
If we subtract 364 from 430, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final outcome is 7034.74725274, with a leftover of 6.6e-08.
