Let's divide 30690147 by 143
We want to figure out the number of times 30690147 can be divided by 143.

Moving on to step 1:
If we divide 3 by 143, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 143

Moving on to step 2:
143 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 143

Step 3:
306 divided by 143 is 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 286 from 306 and we're left with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 143

Going ahead to step 4:
209 divided by 143 is 1 with a remainder of 66.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 143 from 209 leaves us with 66.
Bring next digit (0) of the dividend behind the 66 and repeat the process: 660 / 143

Moving on to step 5:
143 goes into 660 4 times with a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 214.0
If we subtract 572 from 660, we get 88.
Include the next digit (1) from the dividend after 88, then repeat: 881 / 143

Advancing to step 6:
143 goes into 881 6 times with a remainder of 23.
The next digit of our result is 6. 
Result so far: 2146.0
Deduct 858 from 881 and we're left with 23.
Fetch the next digit (4) from the dividend, attach it to 23 and continue: 234 / 143

Going ahead to step 7:
143 can be fit into 234 1 times, resulting in a remainder of 91.
Write down 1 as next digit of the result. 
Result so far: 21461.0
Subtract 143 from 234 to get 91.
Append the next digit (7) from the dividend to 91 and continue with: 917 / 143

Going ahead to step 8:
143 can be fit into 917 6 times, resulting in a remainder of 59.
Record the quotient 6 as the next digit in the result. 
Result so far: 214616.0
Deduct 858 from 917 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 9:
143 goes into 590 4 times with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 214616.4
The remainder is 18 after subtracting 572 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
143 can be fit into 180 1 times, resulting in a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 214616.41
Subtract 143 from 180 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 11:
143 can be fit into 370 2 times, resulting in a remainder of 84.
Write down 2 as next digit of the result. 
Result so far: 214616.412
Subtracting 286 from 370 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 12:
If we divide 840 by 143, we get 5 and a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 214616.4125
The remainder is 125 after subtracting 715 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 13:
The number 143 fits into 1250 8 times, leaving a remainder of 106.
Write down 8 as next digit of the result. 
Result so far: 214616.41258
Subtract 1144 from 1250 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 14:
143 can be fit into 1060 7 times, resulting in a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 214616.412587
Subtract 1001 from 1060 to 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.

Moving on to step 15:
If we divide 590 by 143, we get 4 and a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 214616.4125874
If we take 572 away from 590, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 16:
The number 143 fits into 180 1 times, leaving a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 214616.41258741
If we take 143 away from 180, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

In conclusion, the division gives 214616.41258741 with a balance of 3.7e-08.
