We divide 89994347 by 640
We're looking to find how many times 640 goes into 89994347.

Step 1:
If we divide 8 by 640, we get 0 and 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.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 640

Let's proceed to step 2:
640 goes into 89 0 times with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Grab the next digit (9) from the dividend, add it to 89, then carry on: 899 / 640

On to step 3:
If we divide 899 by 640, we get 1 and a remainder of 259.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 640 from 899 to get 259.
Bring next digit (9) of the dividend behind the 259 and repeat the process: 2599 / 640

Let's proceed to step 4:
640 goes into 2599 4 times with a remainder of 39.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 2560 from 2599 to get 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 640

Going ahead to step 5:
If we divide 394 by 640, we get 0 and a remainder of 394.
Write down 0 as next digit of the result. 
Result so far: 140.0
Subtract 0 from 394 to get 394.
Grab the next digit (3) from the dividend, add it to 394, then carry on: 3943 / 640

On to step 6:
The number 640 fits into 3943 6 times, leaving a remainder of 103.
The next digit of our result is 6. 
Result so far: 1406.0
Subtracting 3840 from 3943 leaves us with 103.
Append the next digit (4) from the dividend to 103 and continue with: 1034 / 640

Advancing to step 7:
The number 640 fits into 1034 1 times, leaving a remainder of 394.
The next digit of our result is 1. 
Result so far: 14061.0
If we subtract 640 from 1034, we get 394.
Grab the next digit (7) from the dividend, add it to 394, then carry on: 3947 / 640

Advancing to step 8:
The number 640 fits into 3947 6 times, leaving a remainder of 107.
Put 6 as the next digit of the answer. 
Result so far: 140616.0
Subtracting 3840 from 3947 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Going ahead to step 9:
The number 640 fits into 1070 1 times, leaving a remainder of 430.
Use 1 as the next digit of our solution. 
Result so far: 140616.1
Subtracting 640 from 1070 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

On to step 10:
4300 divided by 640 is 6 with a remainder of 460.
The number 6 becomes the next digit in our result. 
Result so far: 140616.16
If we subtract 3840 from 4300, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 11:
The number 640 fits into 4600 7 times, leaving a remainder of 120.
Put 7 as the next digit of the answer. 
Result so far: 140616.167
Subtract 4480 from 4600 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 12:
1200 divided by 640 is 1 with a remainder of 560.
Write down 1 as next digit of the result. 
Result so far: 140616.1671
Subtracting 640 from 1200 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 13:
When dividing 5600 by 640, we get 8 with a remainder of 480.
Write down 8 as next digit of the result. 
Result so far: 140616.16718
If we subtract 5120 from 5600, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 14:
If we divide 4800 by 640, we get 7 and a remainder of 320.
The next digit of our result is 7. 
Result so far: 140616.167187
The remainder is 320 after subtracting 4480 from 4800.
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 15:
The number 640 fits into 3200 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 140616.1671875
Subtracting 3200 from 3200 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 16:
The number 640 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 140616.1671875
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 140616.1671875 and a remainder of 0.0.
