64921403 divided by 143 
We want to divide 64921403 by 143.

On to step 1:
If we divide 6 by 143, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 143

Let's proceed to step 2:
The number 143 fits into 64 0 times, leaving a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (9) from the dividend to 64 and continue with: 649 / 143

Step 3:
When dividing 649 by 143, we get 4 with a remainder of 77.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 572 from 649 to get 77.
Fetch the next digit (2) from the dividend, attach it to 77 and continue: 772 / 143

Advancing to step 4:
The number 143 fits into 772 5 times, leaving a remainder of 57.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtracting 715 from 772 leaves us with 57.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 143

Moving on to step 5:
571 divided by 143 is 3 with a remainder of 142.
Put 3 as the next digit of the answer. 
Result so far: 453.0
Subtracting 429 from 571 leaves us with 142.
Append the next digit (4) from the dividend to 142 and continue with: 1424 / 143

Advancing to step 6:
The number 143 fits into 1424 9 times, leaving a remainder of 137.
Use 9 as the next digit of our solution. 
Result so far: 4539.0
Subtracting 1287 from 1424 leaves us with 137.
Grab the next digit (0) from the dividend, add it to 137, then carry on: 1370 / 143

Going ahead to step 7:
If we divide 1370 by 143, we get 9 and a remainder of 83.
Put 9 as the next digit of the answer. 
Result so far: 45399.0
If we subtract 1287 from 1370, we get 83.
Take the next digit (3) from the dividend and append it to 83, then repeat: 833 / 143

Going ahead to step 8:
The number 143 fits into 833 5 times, leaving a remainder of 118.
Put 5 as the next digit of the answer. 
Result so far: 453995.0
Subtracting 715 from 833 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 9:
143 can be fit into 1180 8 times, resulting in a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 453995.8
Deduct 1144 from 1180 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
If we divide 360 by 143, we get 2 and a remainder of 74.
Write down 2 as next digit of the result. 
Result so far: 453995.82
The remainder is 74 after subtracting 286 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 11:
740 divided by 143 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 453995.825
If we take 715 away from 740, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 12:
When dividing 250 by 143, we get 1 with a remainder of 107.
The next digit of our result is 1. 
Result so far: 453995.8251
If we subtract 143 from 250, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Step 13:
When dividing 1070 by 143, we get 7 with a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 453995.82517
If we take 1001 away from 1070, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 14:
143 goes into 690 4 times with a remainder of 118.
Record the quotient 4 as the next digit in the result. 
Result so far: 453995.825174
Deduct 572 from 690 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 15:
If we divide 1180 by 143, we get 8 and a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 453995.8251748
If we subtract 1144 from 1180, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 16:
When dividing 360 by 143, we get 2 with a remainder of 74.
Write down 2 as next digit of the result. 
Result so far: 453995.82517482
Subtracting 286 from 360 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

After the division, we end up with 453995.82517482 and a remainder of 7.4e-08.
