10651142 ÷ 645 
We want to divide 10651142 by 645.

Going ahead to step 1:
645 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 645

Moving on to step 2:
645 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 645

Step 3:
When dividing 106 by 645, we get 0 with a remainder of 106.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 106, we end up with 106.
Grab the next digit (5) from the dividend, add it to 106, then carry on: 1065 / 645

Let's proceed to step 4:
If we divide 1065 by 645, we get 1 and a remainder of 420.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 645 from 1065 and we're left with 420.
Grab the next digit (1) from the dividend, add it to 420, then carry on: 4201 / 645

On to step 5:
If we divide 4201 by 645, we get 6 and a remainder of 331.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 3870 from 4201 to get 331.
Append the next digit (1) from the dividend to 331 and continue with: 3311 / 645

Step 6:
645 can be fit into 3311 5 times, resulting in a remainder of 86.
The next digit of our result is 5. 
Result so far: 165.0
If we take 3225 away from 3311, we end up with 86.
Take the next digit (4) from the dividend and append it to 86, then repeat: 864 / 645

Step 7:
When dividing 864 by 645, we get 1 with a remainder of 219.
Write down 1 as next digit of the result. 
Result so far: 1651.0
Deduct 645 from 864 and we're left with 219.
Take the next digit (2) from the dividend and append it to 219, then repeat: 2192 / 645

Let's proceed to step 8:
2192 divided by 645 is 3 with a remainder of 257.
The next digit of our result is 3. 
Result so far: 16513.0
If we take 1935 away from 2192, we end up with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Advancing to step 9:
645 can be fit into 2570 3 times, resulting in a remainder of 635.
The next digit of our result is 3. 
Result so far: 16513.3
Subtract 1935 from 2570 to get 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Advancing to step 10:
The number 645 fits into 6350 9 times, leaving a remainder of 545.
Put 9 as the next digit of the answer. 
Result so far: 16513.39
If we take 5805 away from 6350, we end up with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Advancing to step 11:
5450 divided by 645 is 8 with a remainder of 290.
Record the quotient 8 as the next digit in the result. 
Result so far: 16513.398
Deduct 5160 from 5450 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 12:
645 can be fit into 2900 4 times, resulting in a remainder of 320.
Use 4 as the next digit of our solution. 
Result so far: 16513.3984
If we take 2580 away from 2900, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 13:
645 goes into 3200 4 times with a remainder of 620.
Use 4 as the next digit of our solution. 
Result so far: 16513.39844
The remainder is 620 after subtracting 2580 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

In conclusion, the division gives 16513.39844 with a balance of 0.00062.
