We divide 30586702 by 142
We want to divide 30586702 by 142.

Step 1:
When dividing 3 by 142, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 142

Moving on to step 2:
If we divide 30 by 142, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Take the next digit (5) from the dividend and append it to 30, then repeat: 305 / 142

Advancing to step 3:
When dividing 305 by 142, we get 2 with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 284 from 305, we get 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 142

Step 4:
218 divided by 142 is 1 with a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 142 from 218 to get 76.
Bring next digit (6) of the dividend behind the 76 and repeat the process: 766 / 142

Advancing to step 5:
142 goes into 766 5 times with a remainder of 56.
Use 5 as the next digit of our solution. 
Result so far: 215.0
The remainder is 56 after subtracting 710 from 766.
Fetch the next digit (7) from the dividend, attach it to 56 and continue: 567 / 142

On to step 6:
142 goes into 567 3 times with a remainder of 141.
Put 3 as the next digit of the answer. 
Result so far: 2153.0
Subtract 426 from 567 to get 141.
Fetch the next digit (0) from the dividend, attach it to 141 and continue: 1410 / 142

Advancing to step 7:
The number 142 fits into 1410 9 times, leaving a remainder of 132.
Write down 9 as next digit of the result. 
Result so far: 21539.0
Deduct 1278 from 1410 and we're left with 132.
Grab the next digit (2) from the dividend, add it to 132, then carry on: 1322 / 142

Step 8:
142 goes into 1322 9 times with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 215399.0
If we take 1278 away from 1322, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
When dividing 440 by 142, we get 3 with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 215399.3
If we subtract 426 from 440, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
When dividing 140 by 142, we get 0 with a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 215399.3
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
142 can be fit into 1400 9 times, resulting in a remainder of 122.
The next digit of our result is 9. 
Result so far: 215399.309
Deduct 1278 from 1400 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 12:
142 can be fit into 1220 8 times, resulting in a remainder of 84.
Record the quotient 8 as the next digit in the result. 
Result so far: 215399.3098
Deduct 1136 from 1220 and we're left 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.

Going ahead to step 13:
840 divided by 142 is 5 with a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 215399.30985
Deduct 710 from 840 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 14:
142 goes into 1300 9 times with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 215399.309859
Subtract 1278 from 1300 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 15:
142 goes into 220 1 times with a remainder of 78.
Use 1 as the next digit of our solution. 
Result so far: 215399.3098591
Subtract 142 from 220 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 16:
142 goes into 780 5 times with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 215399.30985915
Subtract 710 from 780 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 215399.30985915 with a remainder of 7e-08.
