We divide 89169520 by 641
We want to figure out the number of times 89169520 can be divided by 641.

Let's proceed to step 1:
8 divided by 641 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 641

Step 2:
641 can be fit into 89 0 times, resulting in a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Take the next digit (1) from the dividend and append it to 89, then repeat: 891 / 641

Going ahead to step 3:
641 can be fit into 891 1 times, resulting in a remainder of 250.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 641 from 891, we get 250.
Take the next digit (6) from the dividend and append it to 250, then repeat: 2506 / 641

Advancing to step 4:
When dividing 2506 by 641, we get 3 with a remainder of 583.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 1923 from 2506, we get 583.
Bring next digit (9) of the dividend behind the 583 and repeat the process: 5839 / 641

Let's proceed to step 5:
641 goes into 5839 9 times with a remainder of 70.
Put 9 as the next digit of the answer. 
Result so far: 139.0
Subtract 5769 from 5839 to get 70.
Bring next digit (5) of the dividend behind the 70 and repeat the process: 705 / 641

Step 6:
705 divided by 641 is 1 with a remainder of 64.
The number 1 becomes the next digit in our result. 
Result so far: 1391.0
The remainder is 64 after subtracting 641 from 705.
Fetch the next digit (2) from the dividend, attach it to 64 and continue: 642 / 641

Advancing to step 7:
If we divide 642 by 641, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 13911.0
Subtracting 641 from 642 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 641

On to step 8:
If we divide 10 by 641, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 139110.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
When dividing 100 by 641, we get 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 139110.0
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 10:
When dividing 1000 by 641, we get 1 with a remainder of 359.
Put 1 as the next digit of the answer. 
Result so far: 139110.01
If we take 641 away from 1000, we end up with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Step 11:
3590 divided by 641 is 5 with a remainder of 385.
The number 5 becomes the next digit in our result. 
Result so far: 139110.015
If we take 3205 away from 3590, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Moving on to step 12:
When dividing 3850 by 641, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 139110.0156
If we take 3846 away from 3850, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
641 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 139110.0156
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
641 can be fit into 400 0 times, resulting in a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 139110.0156
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 139110.0156, and the remainder is 4e-05.
