Let's divide 90073889 by 610
We want to figure out the number of times 90073889 can be divided by 610.

Advancing to step 1:
610 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 610

Moving on to step 2:
90 divided by 610 is 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Bring next digit (0) of the dividend behind the 90 and repeat the process: 900 / 610

On to step 3:
If we divide 900 by 610, we get 1 and a remainder of 290.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 290 after subtracting 610 from 900.
Fetch the next digit (7) from the dividend, attach it to 290 and continue: 2907 / 610

Advancing to step 4:
2907 divided by 610 is 4 with a remainder of 467.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 2440 from 2907 and we're left with 467.
Grab the next digit (3) from the dividend, add it to 467, then carry on: 4673 / 610

Going ahead to step 5:
4673 divided by 610 is 7 with a remainder of 403.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.0
Deduct 4270 from 4673 and we're left with 403.
Grab the next digit (8) from the dividend, add it to 403, then carry on: 4038 / 610

On to step 6:
The number 610 fits into 4038 6 times, leaving a remainder of 378.
Write down 6 as next digit of the result. 
Result so far: 1476.0
Deduct 3660 from 4038 and we're left with 378.
Include the next digit (8) from the dividend after 378, then repeat: 3788 / 610

Going ahead to step 7:
When dividing 3788 by 610, we get 6 with a remainder of 128.
Use 6 as the next digit of our solution. 
Result so far: 14766.0
If we take 3660 away from 3788, we end up with 128.
Append the next digit (9) from the dividend to 128 and continue with: 1289 / 610

Moving on to step 8:
If we divide 1289 by 610, we get 2 and a remainder of 69.
The number 2 becomes the next digit in our result. 
Result so far: 147662.0
Subtract 1220 from 1289 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 9:
610 goes into 690 1 times with a remainder of 80.
The next digit of our result is 1. 
Result so far: 147662.1
Subtract 610 from 690 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
800 divided by 610 is 1 with a remainder of 190.
Record the quotient 1 as the next digit in the result. 
Result so far: 147662.11
Deduct 610 from 800 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The final outcome is 147662.11, with a leftover of 0.19.
