We're dividing 69006545 by 143 
We want to divide 69006545 by 143.

On to step 1:
143 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 143

Moving on to step 2:
69 divided by 143 is 0 with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Fetch the next digit (0) from the dividend, attach it to 69 and continue: 690 / 143

Moving on to step 3:
The number 143 fits into 690 4 times, leaving a remainder of 118.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 572 away from 690, we end up with 118.
Grab the next digit (0) from the dividend, add it to 118, then carry on: 1180 / 143

Step 4:
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: 48.0
If we take 1144 away from 1180, we end up with 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 143

On to step 5:
366 divided by 143 is 2 with a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 482.0
Deduct 286 from 366 and we're left with 80.
Append the next digit (5) from the dividend to 80 and continue with: 805 / 143

Let's proceed to step 6:
805 divided by 143 is 5 with a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 4825.0
If we take 715 away from 805, we end up with 90.
Bring next digit (4) of the dividend behind the 90 and repeat the process: 904 / 143

Moving on to step 7:
904 divided by 143 is 6 with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 48256.0
Subtracting 858 from 904 leaves us with 46.
Bring next digit (5) of the dividend behind the 46 and repeat the process: 465 / 143

On to step 8:
The number 143 fits into 465 3 times, leaving a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 482563.0
If we subtract 429 from 465, 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.

Moving on to step 9:
360 divided by 143 is 2 with a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 482563.2
Subtract 286 from 360 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 10:
740 divided by 143 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 482563.25
If we subtract 715 from 740, we 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.

Going ahead to step 11:
If we divide 250 by 143, we get 1 and a remainder of 107.
Write down 1 as next digit of the result. 
Result so far: 482563.251
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.

Moving on to step 12:
The number 143 fits into 1070 7 times, leaving a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 482563.2517
Deduct 1001 from 1070 and we're left 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.

Let's proceed to step 13:
143 can be fit into 690 4 times, resulting in a remainder of 118.
The number 4 becomes the next digit in our result. 
Result so far: 482563.25174
If we subtract 572 from 690, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 14:
When dividing 1180 by 143, we get 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 482563.251748
The remainder is 36 after subtracting 1144 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 15:
143 goes into 360 2 times with a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 482563.2517482
Deduct 286 from 360 and we're left 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.

On to step 16:
740 divided by 143 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 482563.25174825
If we subtract 715 from 740, we 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.

The final outcome is 482563.25174825, with a leftover of 2.5e-08.
