Let's divide 87438221 by 558
We want to figure out the number of times 87438221 can be divided by 558.

Advancing to step 1:
The number 558 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
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 / 558

Moving on to step 2:
The number 558 fits into 87 0 times, leaving a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Grab the next digit (4) from the dividend, add it to 87, then carry on: 874 / 558

Step 3:
558 can be fit into 874 1 times, resulting in a remainder of 316.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 558 from 874 leaves us with 316.
Grab the next digit (3) from the dividend, add it to 316, then carry on: 3163 / 558

Step 4:
The number 558 fits into 3163 5 times, leaving a remainder of 373.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 2790 from 3163 leaves us with 373.
Take the next digit (8) from the dividend and append it to 373, then repeat: 3738 / 558

Going ahead to step 5:
558 can be fit into 3738 6 times, resulting in a remainder of 390.
The next digit of our result is 6. 
Result so far: 156.0
The remainder is 390 after subtracting 3348 from 3738.
Bring next digit (2) of the dividend behind the 390 and repeat the process: 3902 / 558

Advancing to step 6:
558 goes into 3902 6 times with a remainder of 554.
The next digit of our result is 6. 
Result so far: 1566.0
If we take 3348 away from 3902, we end up with 554.
Include the next digit (2) from the dividend after 554, then repeat: 5542 / 558

Advancing to step 7:
If we divide 5542 by 558, we get 9 and a remainder of 520.
The number 9 becomes the next digit in our result. 
Result so far: 15669.0
If we subtract 5022 from 5542, we get 520.
Fetch the next digit (1) from the dividend, attach it to 520 and continue: 5201 / 558

Going ahead to step 8:
The number 558 fits into 5201 9 times, leaving a remainder of 179.
Use 9 as the next digit of our solution. 
Result so far: 156699.0
If we take 5022 away from 5201, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 9:
If we divide 1790 by 558, we get 3 and a remainder of 116.
The number 3 becomes the next digit in our result. 
Result so far: 156699.3
If we take 1674 away from 1790, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 10:
When dividing 1160 by 558, we get 2 with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 156699.32
Deduct 1116 from 1160 and we're left 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.

Step 11:
When dividing 440 by 558, we get 0 with a remainder of 440.
The next digit of our result is 0. 
Result so far: 156699.32
Subtract 0 from 440 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 12:
When dividing 4400 by 558, we get 7 with a remainder of 494.
Put 7 as the next digit of the answer. 
Result so far: 156699.3207
If we subtract 3906 from 4400, we get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Moving on to step 13:
The number 558 fits into 4940 8 times, leaving a remainder of 476.
Put 8 as the next digit of the answer. 
Result so far: 156699.32078
Subtracting 4464 from 4940 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 14:
The number 558 fits into 4760 8 times, leaving a remainder of 296.
The next digit of our result is 8. 
Result so far: 156699.320788
If we subtract 4464 from 4760, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

In conclusion, the division gives 156699.320788 with a balance of 2.96e-05.
