91414340 ÷ 644 
Let's see how many times 644 fits into 91414340.

Advancing to step 1:
9 divided by 644 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 644

Advancing to step 2:
The number 644 fits into 91 0 times, leaving a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Grab the next digit (4) from the dividend, add it to 91, then carry on: 914 / 644

Advancing to step 3:
If we divide 914 by 644, we get 1 and a remainder of 270.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 644 from 914 to get 270.
Grab the next digit (1) from the dividend, add it to 270, then carry on: 2701 / 644

Advancing to step 4:
When dividing 2701 by 644, we get 4 with a remainder of 125.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 2576 from 2701 and we're left with 125.
Include the next digit (4) from the dividend after 125, then repeat: 1254 / 644

Let's proceed to step 5:
1254 divided by 644 is 1 with a remainder of 610.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
If we subtract 644 from 1254, we get 610.
Include the next digit (3) from the dividend after 610, then repeat: 6103 / 644

Advancing to step 6:
When dividing 6103 by 644, we get 9 with a remainder of 307.
Use 9 as the next digit of our solution. 
Result so far: 1419.0
Subtract 5796 from 6103 to get 307.
Bring next digit (4) of the dividend behind the 307 and repeat the process: 3074 / 644

Going ahead to step 7:
If we divide 3074 by 644, we get 4 and a remainder of 498.
Write down 4 as next digit of the result. 
Result so far: 14194.0
If we take 2576 away from 3074, we end up with 498.
Fetch the next digit (0) from the dividend, attach it to 498 and continue: 4980 / 644

Let's proceed to step 8:
4980 divided by 644 is 7 with a remainder of 472.
The number 7 becomes the next digit in our result. 
Result so far: 141947.0
If we take 4508 away from 4980, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Moving on to step 9:
644 can be fit into 4720 7 times, resulting in a remainder of 212.
Put 7 as the next digit of the answer. 
Result so far: 141947.7
Deduct 4508 from 4720 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 10:
When dividing 2120 by 644, we get 3 with a remainder of 188.
The next digit of our result is 3. 
Result so far: 141947.73
If we subtract 1932 from 2120, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 11:
1880 divided by 644 is 2 with a remainder of 592.
Write down 2 as next digit of the result. 
Result so far: 141947.732
If we subtract 1288 from 1880, we get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

On to step 12:
644 can be fit into 5920 9 times, resulting in a remainder of 124.
Record the quotient 9 as the next digit in the result. 
Result so far: 141947.7329
Subtract 5796 from 5920 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 13:
644 goes into 1240 1 times with a remainder of 596.
The next digit of our result is 1. 
Result so far: 141947.73291
Deduct 644 from 1240 and we're left with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

On to step 14:
If we divide 5960 by 644, we get 9 and a remainder of 164.
Record the quotient 9 as the next digit in the result. 
Result so far: 141947.732919
Subtract 5796 from 5960 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 15:
When dividing 1640 by 644, we get 2 with a remainder of 352.
The number 2 becomes the next digit in our result. 
Result so far: 141947.7329192
The remainder is 352 after subtracting 1288 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 16:
The number 644 fits into 3520 5 times, leaving a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 141947.73291925
If we take 3220 away from 3520, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The quotient of the division is 141947.73291925, and the remainder is 3e-07.
