We divide 80346170 by 142
Our goal is to divide 80346170 by 142.

Step 1:
When dividing 8 by 142, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 142

Going ahead to step 2:
142 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Take the next digit (3) from the dividend and append it to 80, then repeat: 803 / 142

Moving on to step 3:
142 can be fit into 803 5 times, resulting in a remainder of 93.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 710 from 803 and we're left with 93.
Take the next digit (4) from the dividend and append it to 93, then repeat: 934 / 142

Moving on to step 4:
The number 142 fits into 934 6 times, leaving a remainder of 82.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
Subtract 852 from 934 to get 82.
Take the next digit (6) from the dividend and append it to 82, then repeat: 826 / 142

Step 5:
If we divide 826 by 142, we get 5 and a remainder of 116.
The next digit of our result is 5. 
Result so far: 565.0
Subtract 710 from 826 to get 116.
Take the next digit (1) from the dividend and append it to 116, then repeat: 1161 / 142

On to step 6:
1161 divided by 142 is 8 with a remainder of 25.
Write down 8 as next digit of the result. 
Result so far: 5658.0
Subtract 1136 from 1161 to get 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 142

Going ahead to step 7:
142 goes into 257 1 times with a remainder of 115.
Record the quotient 1 as the next digit in the result. 
Result so far: 56581.0
Deduct 142 from 257 and we're left with 115.
Append the next digit (0) from the dividend to 115 and continue with: 1150 / 142

Advancing to step 8:
The number 142 fits into 1150 8 times, leaving a remainder of 14.
The next digit of our result is 8. 
Result so far: 565818.0
The remainder is 14 after subtracting 1136 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
142 goes into 140 0 times with a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 565818.0
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 10:
The number 142 fits into 1400 9 times, leaving a remainder of 122.
Use 9 as the next digit of our solution. 
Result so far: 565818.09
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.

Going ahead to step 11:
142 goes into 1220 8 times with a remainder of 84.
The next digit of our result is 8. 
Result so far: 565818.098
If we take 1136 away from 1220, we end up 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.

Let's proceed to step 12:
840 divided by 142 is 5 with a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 565818.0985
Subtracting 710 from 840 leaves us 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.

Advancing to step 13:
142 goes into 1300 9 times with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 565818.09859
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.

On to step 14:
The number 142 fits into 220 1 times, leaving a remainder of 78.
Use 1 as the next digit of our solution. 
Result so far: 565818.098591
The remainder is 78 after subtracting 142 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 15:
The number 142 fits into 780 5 times, leaving a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 565818.0985915
Deduct 710 from 780 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 16:
The number 142 fits into 700 4 times, leaving a remainder of 132.
Record the quotient 4 as the next digit in the result. 
Result so far: 565818.09859154
If we take 568 away from 700, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The final result is 565818.09859154 with a remainder of 1.32e-07.
