We look at the division of 90139501 by 446 
We want to figure out the number of times 90139501 can be divided by 446.

Moving on to step 1:
If we divide 9 by 446, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 446

On to step 2:
The number 446 fits into 90 0 times, leaving a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Take the next digit (1) from the dividend and append it to 90, then repeat: 901 / 446

Moving on to step 3:
446 goes into 901 2 times with a remainder of 9.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 892 from 901, we get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 446

On to step 4:
When dividing 93 by 446, we get 0 with a remainder of 93.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we take 0 away from 93, we end up with 93.
Bring next digit (9) of the dividend behind the 93 and repeat the process: 939 / 446

Advancing to step 5:
If we divide 939 by 446, we get 2 and a remainder of 47.
Use 2 as the next digit of our solution. 
Result so far: 202.0
Subtracting 892 from 939 leaves us with 47.
Grab the next digit (5) from the dividend, add it to 47, then carry on: 475 / 446

On to step 6:
446 goes into 475 1 times with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 2021.0
If we take 446 away from 475, we end up with 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 446

Moving on to step 7:
290 divided by 446 is 0 with a remainder of 290.
The next digit of our result is 0. 
Result so far: 20210.0
Subtracting 0 from 290 leaves us with 290.
Bring next digit (1) of the dividend behind the 290 and repeat the process: 2901 / 446

Going ahead to step 8:
446 can be fit into 2901 6 times, resulting in a remainder of 225.
Record the quotient 6 as the next digit in the result. 
Result so far: 202106.0
The remainder is 225 after subtracting 2676 from 2901.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 9:
446 can be fit into 2250 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 202106.5
Subtracting 2230 from 2250 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
If we divide 200 by 446, we get 0 and a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 202106.5
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
2000 divided by 446 is 4 with a remainder of 216.
Use 4 as the next digit of our solution. 
Result so far: 202106.504
The remainder is 216 after subtracting 1784 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 12:
If we divide 2160 by 446, we get 4 and a remainder of 376.
Write down 4 as next digit of the result. 
Result so far: 202106.5044
Deduct 1784 from 2160 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

The final outcome is 202106.5044, with a leftover of 0.00376.
