91870562 ÷ 142 
Our goal is to divide 91870562 by 142.

Moving on to step 1:
When dividing 9 by 142, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 142

Step 2:
142 goes into 91 0 times with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Take the next digit (8) from the dividend and append it to 91, then repeat: 918 / 142

Advancing to step 3:
When dividing 918 by 142, we get 6 with a remainder of 66.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 852 from 918, we get 66.
Grab the next digit (7) from the dividend, add it to 66, then carry on: 667 / 142

Advancing to step 4:
If we divide 667 by 142, we get 4 and a remainder of 99.
Write down 4 as next digit of the result. 
Result so far: 64.0
If we take 568 away from 667, we end up with 99.
Fetch the next digit (0) from the dividend, attach it to 99 and continue: 990 / 142

On to step 5:
142 can be fit into 990 6 times, resulting in a remainder of 138.
Record the quotient 6 as the next digit in the result. 
Result so far: 646.0
The remainder is 138 after subtracting 852 from 990.
Grab the next digit (5) from the dividend, add it to 138, then carry on: 1385 / 142

Moving on to step 6:
If we divide 1385 by 142, we get 9 and a remainder of 107.
Record the quotient 9 as the next digit in the result. 
Result so far: 6469.0
Subtract 1278 from 1385 to get 107.
Grab the next digit (6) from the dividend, add it to 107, then carry on: 1076 / 142

On to step 7:
1076 divided by 142 is 7 with a remainder of 82.
The number 7 becomes the next digit in our result. 
Result so far: 64697.0
Subtract 994 from 1076 to get 82.
Include the next digit (2) from the dividend after 82, then repeat: 822 / 142

Advancing to step 8:
When dividing 822 by 142, we get 5 with a remainder of 112.
The next digit of our result is 5. 
Result so far: 646975.0
Deduct 710 from 822 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 9:
142 goes into 1120 7 times with a remainder of 126.
The number 7 becomes the next digit in our result. 
Result so far: 646975.7
Deduct 994 from 1120 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 10:
142 can be fit into 1260 8 times, resulting in a remainder of 124.
Write down 8 as next digit of the result. 
Result so far: 646975.78
Subtracting 1136 from 1260 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 11:
The number 142 fits into 1240 8 times, leaving a remainder of 104.
Record the quotient 8 as the next digit in the result. 
Result so far: 646975.788
Subtract 1136 from 1240 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The quotient of the division is 646975.788, and the remainder is 0.0104.
