87775258 ÷ 141 
Our goal is to divide 87775258 by 141.

Step 1:
141 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 141

Advancing to step 2:
When dividing 87 by 141, we get 0 with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Append the next digit (7) from the dividend to 87 and continue with: 877 / 141

On to step 3:
The number 141 fits into 877 6 times, leaving a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 31 after subtracting 846 from 877.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 141

Going ahead to step 4:
141 can be fit into 317 2 times, resulting in a remainder of 35.
Write down 2 as next digit of the result. 
Result so far: 62.0
If we take 282 away from 317, we end up with 35.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 141

Let's proceed to step 5:
When dividing 355 by 141, we get 2 with a remainder of 73.
The number 2 becomes the next digit in our result. 
Result so far: 622.0
If we take 282 away from 355, we end up with 73.
Take the next digit (2) from the dividend and append it to 73, then repeat: 732 / 141

Let's proceed to step 6:
If we divide 732 by 141, we get 5 and a remainder of 27.
The next digit of our result is 5. 
Result so far: 6225.0
Deduct 705 from 732 and we're left with 27.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 141

Let's proceed to step 7:
If we divide 275 by 141, we get 1 and a remainder of 134.
Put 1 as the next digit of the answer. 
Result so far: 62251.0
Deduct 141 from 275 and we're left with 134.
Grab the next digit (8) from the dividend, add it to 134, then carry on: 1348 / 141

Going ahead to step 8:
The number 141 fits into 1348 9 times, leaving a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 622519.0
If we take 1269 away from 1348, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 9:
If we divide 790 by 141, we get 5 and a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 622519.5
Deduct 705 from 790 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 10:
If we divide 850 by 141, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 622519.56
Subtract 846 from 850 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
The number 141 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 622519.56
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
141 goes into 400 2 times with a remainder of 118.
The number 2 becomes the next digit in our result. 
Result so far: 622519.5602
Deduct 282 from 400 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 13:
141 can be fit into 1180 8 times, resulting in a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 622519.56028
The remainder is 52 after subtracting 1128 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 14:
When dividing 520 by 141, we get 3 with a remainder of 97.
Use 3 as the next digit of our solution. 
Result so far: 622519.560283
Deduct 423 from 520 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Going ahead to step 15:
The number 141 fits into 970 6 times, leaving a remainder of 124.
The next digit of our result is 6. 
Result so far: 622519.5602836
Deduct 846 from 970 and we're left 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.

Going ahead to step 16:
141 goes into 1240 8 times with a remainder of 112.
Put 8 as the next digit of the answer. 
Result so far: 622519.56028368
Deduct 1128 from 1240 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.

The final outcome is 622519.56028368, with a leftover of 1.12e-07.
