We're dividing 90961229 by 578 
We want to divide 90961229 by 578.

Advancing to step 1:
When dividing 9 by 578, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 578

Moving on to step 2:
If we divide 90 by 578, we get 0 and a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Bring next digit (9) of the dividend behind the 90 and repeat the process: 909 / 578

On to step 3:
If we divide 909 by 578, we get 1 and a remainder of 331.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 578 away from 909, we end up with 331.
Take the next digit (6) from the dividend and append it to 331, then repeat: 3316 / 578

Going ahead to step 4:
If we divide 3316 by 578, we get 5 and a remainder of 426.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 426 after subtracting 2890 from 3316.
Include the next digit (1) from the dividend after 426, then repeat: 4261 / 578

Moving on to step 5:
When dividing 4261 by 578, we get 7 with a remainder of 215.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
Deduct 4046 from 4261 and we're left with 215.
Bring next digit (2) of the dividend behind the 215 and repeat the process: 2152 / 578

Moving on to step 6:
2152 divided by 578 is 3 with a remainder of 418.
Put 3 as the next digit of the answer. 
Result so far: 1573.0
If we take 1734 away from 2152, we end up with 418.
Take the next digit (2) from the dividend and append it to 418, then repeat: 4182 / 578

Going ahead to step 7:
When dividing 4182 by 578, we get 7 with a remainder of 136.
Put 7 as the next digit of the answer. 
Result so far: 15737.0
Deduct 4046 from 4182 and we're left with 136.
Include the next digit (9) from the dividend after 136, then repeat: 1369 / 578

Going ahead to step 8:
When dividing 1369 by 578, we get 2 with a remainder of 213.
Write down 2 as next digit of the result. 
Result so far: 157372.0
The remainder is 213 after subtracting 1156 from 1369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Advancing to step 9:
578 goes into 2130 3 times with a remainder of 396.
The number 3 becomes the next digit in our result. 
Result so far: 157372.3
Subtract 1734 from 2130 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 10:
578 can be fit into 3960 6 times, resulting in a remainder of 492.
Write down 6 as next digit of the result. 
Result so far: 157372.36
Subtracting 3468 from 3960 leaves us with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Let's proceed to step 11:
When dividing 4920 by 578, we get 8 with a remainder of 296.
The next digit of our result is 8. 
Result so far: 157372.368
Subtract 4624 from 4920 to 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.

Let's proceed to step 12:
578 can be fit into 2960 5 times, resulting in a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 157372.3685
Subtracting 2890 from 2960 leaves us 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.

Let's proceed to step 13:
700 divided by 578 is 1 with a remainder of 122.
The next digit of our result is 1. 
Result so far: 157372.36851
If we take 578 away from 700, we end up 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.

Let's proceed to step 14:
The number 578 fits into 1220 2 times, leaving a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 157372.368512
Subtract 1156 from 1220 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 15:
When dividing 640 by 578, we get 1 with a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 157372.3685121
If we subtract 578 from 640, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 16:
578 goes into 620 1 times with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 157372.36851211
If we subtract 578 from 620, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 157372.36851211 with a remainder of 4.2e-08.
