87986416 ÷ 658 
We want to figure out the number of times 87986416 can be divided by 658.

Advancing to step 1:
The number 658 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 658

On to step 2:
658 can be fit into 87 0 times, resulting in a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Grab the next digit (9) from the dividend, add it to 87, then carry on: 879 / 658

Going ahead to step 3:
If we divide 879 by 658, we get 1 and a remainder of 221.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 658 from 879 and we're left with 221.
Include the next digit (8) from the dividend after 221, then repeat: 2218 / 658

On to step 4:
658 goes into 2218 3 times with a remainder of 244.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 1974 away from 2218, we end up with 244.
Bring next digit (6) of the dividend behind the 244 and repeat the process: 2446 / 658

Advancing to step 5:
2446 divided by 658 is 3 with a remainder of 472.
Write down 3 as next digit of the result. 
Result so far: 133.0
Subtract 1974 from 2446 to get 472.
Fetch the next digit (4) from the dividend, attach it to 472 and continue: 4724 / 658

Advancing to step 6:
4724 divided by 658 is 7 with a remainder of 118.
Use 7 as the next digit of our solution. 
Result so far: 1337.0
If we subtract 4606 from 4724, we get 118.
Fetch the next digit (1) from the dividend, attach it to 118 and continue: 1181 / 658

Step 7:
The number 658 fits into 1181 1 times, leaving a remainder of 523.
Record the quotient 1 as the next digit in the result. 
Result so far: 13371.0
If we subtract 658 from 1181, we get 523.
Include the next digit (6) from the dividend after 523, then repeat: 5236 / 658

Advancing to step 8:
When dividing 5236 by 658, we get 7 with a remainder of 630.
Put 7 as the next digit of the answer. 
Result so far: 133717.0
Subtract 4606 from 5236 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

On to step 9:
When dividing 6300 by 658, we get 9 with a remainder of 378.
Write down 9 as next digit of the result. 
Result so far: 133717.9
Deduct 5922 from 6300 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Step 10:
658 can be fit into 3780 5 times, resulting in a remainder of 490.
Record the quotient 5 as the next digit in the result. 
Result so far: 133717.95
If we subtract 3290 from 3780, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Going ahead to step 11:
If we divide 4900 by 658, we get 7 and a remainder of 294.
Write down 7 as next digit of the result. 
Result so far: 133717.957
If we subtract 4606 from 4900, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Step 12:
When dividing 2940 by 658, we get 4 with a remainder of 308.
The next digit of our result is 4. 
Result so far: 133717.9574
The remainder is 308 after subtracting 2632 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 13:
3080 divided by 658 is 4 with a remainder of 448.
The number 4 becomes the next digit in our result. 
Result so far: 133717.95744
Subtracting 2632 from 3080 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

The final outcome is 133717.95744, with a leftover of 0.000448.
